feat(frontend): Add comprehensive bank account management system.

- Add drawer-based bank account connection flow with country/bank selection - Create bank connection success page with redirect handling - Add bank connections status card showing all requisitions and their states - Move account management actions to appropriate sections (add to connections, edit in accounts) - Implement proper delete functionality for bank connections via GoCardless API - Add proper TypeScript types for all bank-related data structures - Improve error handling for bank connection operations with specific HTTP status codes - Remove transaction data when disconnecting accounts while preserving history 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
