chore(ci): Bump version to 2025.10.1

Replace inconsistent native HTML button elements with shadcn/ui Button
component across all components for consistent styling and behavior.

Changes:
- TransactionsTable: Use Button with ghost variant for Raw action buttons
- Settings: Standardize edit, save, cancel, and delete buttons with icon variant
- AccountsOverview: Apply consistent Button component for account actions
- AccountSettings: Update account editing buttons to use Button component
- NotificationFiltersDrawer: Convert filter removal buttons to Button component

Benefits:
- Consistent design system throughout the app
- Better accessibility and keyboard navigation
- Proper theme support and state handling
- Reduced custom CSS and improved maintainability

+# Agent Guidelines for Leggen
+
+## Quick Setup for Development
+
+### Prerequisites
+- **uv** must be installed for Python dependency management (can be installed via `pip install uv`)
+- **Configuration file**: Copy `config.example.toml` to `config.toml` before running any commands:
+  ```bash
+  cp config.example.toml config.toml
+  ```
+
+### Generate Mock Database
+The leggen CLI provides a command to generate a mock database for testing:
+
+```bash
+# Generate sample database with default settings (3 accounts, 50 transactions each)
+uv run leggen --config config.toml generate_sample_db --database /path/to/test.db --force
+
+# Custom configuration
+uv run leggen --config config.toml generate_sample_db --database ./test-data.db --accounts 5 --transactions 100 --force
+```
+
+The command outputs instructions for setting the required environment variable to use the generated database.
+
+### Start the API Server
+1. Install uv if not already installed: `pip install uv`
+2. Set the database environment variable to point to your generated mock database:
+   ```bash
+   export LEGGEN_DATABASE_PATH=/path/to/your/generated/database.db
+   ```
+3. Ensure the API can find the configuration file (choose one):
+   ```bash
+   # Option 1: Copy config to the expected location
+   mkdir -p ~/.config/leggen && cp config.toml ~/.config/leggen/config.toml
+   
+   # Option 2: Set environment variable to current config file
+   export LEGGEN_CONFIG_FILE=./config.toml
+   ```
+4. Start the API server:
+   ```bash
+   uv run leggen server
+   ```
+   - For development mode with auto-reload: `uv run leggen server --reload`
+   - API will be available at `http://localhost:8000` with docs at `http://localhost:8000/api/v1/docs`
+
+### Start the Frontend
+1. Navigate to the frontend directory: `cd frontend`
+2. Install npm dependencies: `npm install`
+3. Start the development server: `npm run dev`
+   - Frontend will be available at `http://localhost:3000`
+   - The frontend is configured to connect to the API at `http://localhost:8000/api/v1`
+
+## Build/Lint/Test Commands
+
+### Frontend (React/TypeScript)
+- **Dev server**: `cd frontend && npm run dev`
+- **Build**: `cd frontend && npm run build`
+- **Lint**: `cd frontend && npm run lint`
+
+### Backend (Python)
+- **Lint**: `uv run ruff check .`
+- **Format**: `uv run ruff format .`
+- **Type check**: `uv run mypy leggen --check-untyped-defs`
+- **All checks**: `uv run pre-commit run --all-files`
+- **Run all tests**: `uv run pytest`
+- **Run single test**: `uv run pytest tests/unit/test_api_accounts.py::TestAccountsAPI::test_get_all_accounts_success -v`
+- **Run tests by marker**: `uv run pytest -m "api"` or `uv run pytest -m "unit"`
+
+## Code Style Guidelines
+
+### Python
+- **Imports**: Standard library → Third-party → Local (blank lines between groups)
+- **Naming**: snake_case for variables/functions, PascalCase for classes
+- **Types**: Use type hints for all function parameters and return values
+- **Error handling**: Use specific exceptions, loguru for logging
+- **Path handling**: Use `pathlib.Path` instead of `os.path`
+- **CLI**: Use Click framework with proper option decorators
+
+### TypeScript/React
+- **Imports**: React hooks first, then third-party, then local components/types
+- **Naming**: PascalCase for components, camelCase for variables/functions
+- **Types**: Use `import type` for type-only imports, define interfaces/types
+- **Styling**: Tailwind CSS with `clsx` utility for conditional classes
+- **UI Components**: shadcn/ui components for consistent design system
+- **Icons**: lucide-react with consistent naming
+- **Data fetching**: @tanstack/react-query with proper error handling
+- **Components**: Functional components with hooks, proper TypeScript typing
+
+## Frontend Structure
+
+### Layout Architecture
+- **Root Layout**: `frontend/src/routes/__root.tsx` - Contains main app structure with Sidebar and Header
+- **Header/Navbar**: `frontend/src/components/Header.tsx` - Top navigation bar (sticky on mobile only)
+- **Sidebar**: `frontend/src/components/Sidebar.tsx` - Left navigation sidebar
+- **Routes**: `frontend/src/routes/` - TanStack Router file-based routing
+
+### Key Components Location
+- **UI Components**: `frontend/src/components/ui/` - shadcn/ui components and reusable UI primitives
+- **Feature Components**: `frontend/src/components/` - Main app components
+- **Pages**: `frontend/src/routes/` - Route components (index.tsx, transactions.tsx, etc.)
+- **Hooks**: `frontend/src/hooks/` - Custom React hooks
+- **API**: `frontend/src/lib/api.ts` - API client configuration
+- **Context**: `frontend/src/contexts/` - React contexts (ThemeContext, etc.)
+
+### Routing Structure
+- `/` - Overview/Dashboard (TransactionsTable component)
+- `/transactions` - Transactions page
+- `/analytics` - Analytics page
+- `/notifications` - Notifications page
+- `/settings` - Settings page
+
+### General
+- **Formatting**: ruff for Python, ESLint for TypeScript
+- **Commits**: Use conventional commits with optional scopes, run pre-commit hooks before pushing
+  - Format: `type(scope): Description starting with uppercase and ending with period.`
+  - Scopes: `cli`, `api`, `frontend` (optional)
+  - Types: `feat`, `fix`, `refactor` (avoid too many different types)
+  - Examples:
+    - `feat(frontend): Add support for S3 backups.`
+    - `fix(api): Resolve authentication timeout issues.`
+    - `refactor(cli): Improve error handling for missing config.`
+  - Avoid including specific numbers, counts, or data-dependent information that may become outdated
+- **Security**: Never log sensitive data, use environment variables for secrets
+
+## AI Development Support
+
+### shadcn/ui Integration
+This project uses shadcn/ui for consistent UI components. The MCP server is configured for AI agents to:
+- Search and browse available shadcn/ui components
+- View component implementation details and examples
+- Generate proper installation commands for new components
+
+Use the shadcn MCP tools when working with UI components to ensure consistency with the existing design system.
+
+## Contributing Guidelines
+
+This repository follows conventional changelog practices. Refer to `CONTRIBUTING.md` for detailed contribution guidelines including:
+- Commit message format and scoping
+- Release process using `scripts/release.sh`
+- Pre-commit hooks setup with `pre-commit install`
+- When the pre-commit fails, the commit is canceled

-An Open Banking CLI.
 
-This tool aims to provide a simple way to connect to banks using the GoCardless Open Banking API.
+A self hosted Open Banking Dashboard, API and CLI for managing bank connections and transactions.
 
-Having a simple CLI tool to connect to banks and list transactions can be very useful for developers and companies that need to access bank data.
+Having your bank data accessible through both CLI and REST API gives you the power to backup, analyze, create reports, and integrate with other applications.
 
-Having your bank data in a database, gives you the power to backup, analyze and create reports with your data.

+  - [FastAPI](https://fastapi.tiangolo.com/): High-performance async API backend (integrated into `leggen server`)
   - [GoCardless Open Banking API](https://developer.gocardless.com/bank-account-data/overview): for connecting to banks
+  - [APScheduler](https://apscheduler.readthedocs.io/): Background job scheduling with configurable cron
 
   ### 📦 Storage
   - [SQLite](https://www.sqlite.org): for storing transactions, simple and easy to use
-  - [MongoDB](https://www.mongodb.com/docs/): alternative store for transactions, good balance between performance and query capabilities
 
-  ### ⏰ Scheduling
-  - [Ofelia](https://github.com/mcuadros/ofelia): for scheduling regular syncs with the database when using Docker
-
-  ### 📊 Visualization
-  - [NocoDB](https://github.com/nocodb/nocodb): for visualizing and querying transactions, a simple and easy to use interface for SQLite
 
 ## ✨ Features
-  - Connect to banks using GoCardless Open Banking API
-  - List all connected banks and their statuses
-  - List balances of all connected accounts
-  - List transactions for all connected accounts
-  - Sync all transactions with a SQLite and/or MongoDB database
-  - Visualize and query transactions using NocoDB
-  - Schedule regular syncs with the database using Ofelia
-  - Send notifications to Discord and/or Telegram when transactions match certain filters
 
-## 🚀 Installation and Configuration
+### 🎯 Core Banking Features
+- Connect to banks using GoCardless Open Banking API (30+ EU countries)
+- List all connected banks and their connection statuses
+- View balances of all connected accounts
+- List and filter transactions across all accounts
+- Support for both booked and pending transactions
 
-In order to use `leggen`, you need to create a GoCardless account. GoCardless is a service that provides access to Open Banking APIs. You can create an account at https://gocardless.com/bank-account-data/.

-After creating an account and getting your API keys, the best way is to use the [compose file](compose.yml). Open the file and adapt it to your needs.
+### 📡 API & Integration
+- **REST API**: Complete FastAPI backend with comprehensive endpoints
+- **CLI Interface**: Enhanced command-line tools with new options
 
-### Example Configuration
+### 🔔 Notifications & Monitoring
+- Discord and Telegram notifications for filtered transactions
+- Configurable transaction filters (case-sensitive/insensitive)
+- Account expiry notifications and status alerts
+- Comprehensive logging and error handling

-### Running Leggen with Docker
+## 📖 Usage
 
-After adapting the compose file, run the following command:
+### Web Interface
+Access the React web interface at `http://localhost:3000` after starting the services.
 
+### API Service
+Visit `http://localhost:3000/api/v1/docs` for interactive API documentation.
+
+### CLI Commands
 ```bash
-$ docker compose up -d
+leggen status              # Check connection status
+leggen bank add            # Connect to a new bank
+leggen balances            # View account balances
+leggen transactions        # List transactions

+# Leggen Frontend
+
+A modern React dashboard for the Leggen Open Banking CLI tool. This frontend provides a user-friendly interface to view bank accounts, transactions, and balances.
+
+## Features
+
+- **Modern Dashboard**: Clean, responsive interface built with React and TypeScript
+- **Bank Accounts Overview**: View all connected bank accounts with real-time balances
+- **Transaction Management**: Browse, search, and filter transactions across all accounts
+- **Responsive Design**: Works seamlessly on desktop, tablet, and mobile devices
+- **Real-time Data**: Powered by React Query for efficient data fetching and caching
+
+## Prerequisites
+
+- Node.js 18+ and npm
+- Leggen API server running (configurable via environment variables)
+
+## Getting Started
+
+1. **Install dependencies:**
+
+   ```bash
+   npm install
+   ```
+
+2. **Start the development server:**
+
+   ```bash
+   npm run dev
+   ```
+
+3. **Open your browser to:**
+   ```
+   http://localhost:5173
+   ```
+
+## Available Scripts
+
+- `npm run dev` - Start development server
+- `npm run build` - Build for production
+- `npm run preview` - Preview production build
+- `npm run lint` - Run ESLint
+
+## Architecture
+
+### Key Technologies
+
+- **React 18** - Modern React with hooks and concurrent features
+- **TypeScript** - Type-safe JavaScript development
+- **Vite** - Fast build tool and development server
+- **Tailwind CSS** - Utility-first CSS framework
+- **React Query** - Data fetching and caching
+- **Axios** - HTTP client for API calls
+- **Lucide React** - Modern icon library
+
+### Project Structure
+
+```
+src/
+├── components/          # React components
+│   ├── Dashboard.tsx    # Main dashboard layout
+│   ├── AccountsOverview.tsx
+│   └── TransactionsList.tsx
+├── lib/                # Utilities and API client
+│   ├── api.ts          # API client and endpoints
+│   └── utils.ts        # Helper functions

+│   └── api.ts          # API response types
+└── App.tsx             # Main application component
+```
+
+## API Integration
+
+The frontend connects to the Leggen API server (configurable via environment variables). The API client handles:
+
+- Account retrieval and management
+- Transaction fetching with filtering
+- Balance information
+- Error handling and loading states
+
+## Configuration
+
+### API URL Configuration
+
+The frontend supports configurable API URLs through environment variables:
+
+**Development:**
+
+- Set `VITE_API_URL` to call external APIs during development
+- Example: `VITE_API_URL=https://staging-api.example.com npm run dev`
+
+**Production:**
+
+- Uses relative URLs (`/api/v1`) that nginx proxies to the backend
+- Configure nginx proxy target via `API_BACKEND_URL` environment variable
+- Default: `http://leggen-server:8000`
+
+**Docker Compose:**
+
+```bash
+# Override API backend URL
+API_BACKEND_URL=https://prod-api.example.com docker-compose up
+```
+
+## Development
+
+The dashboard is designed to work with the Leggen CLI tool's API endpoints. Make sure your Leggen server is running before starting the frontend development server.
+
+### Adding New Features
+
+1. Define TypeScript types in `src/types/api.ts`
+2. Add API methods to `src/lib/api.ts`
+3. Create React components in `src/components/`
+4. Use React Query for data fetching and state management
+
+## Deployment
+
+Build the application for production:
+
+```bash
+npm run build
+```
+
+The built files will be in the `dist/` directory, ready to be served by any static web server.
