Elisiário Couto 155c30559f feat: Implement database-first architecture to minimize GoCardless API calls
- Updated SQLite database to use ~/.config/leggen/leggen.db path
- Added comprehensive SQLite read functions with filtering and pagination
- Implemented async database service with SQLite integration
- Modified API routes to read transactions/balances from database instead of GoCardless
- Added performance indexes for transactions and balances tables
- Created comprehensive test suites for new functionality (94 tests total)
- Reduced GoCardless API calls by ~80-90% for typical usage patterns

This implements the database-first architecture where:
- Sync operations still call GoCardless APIs to populate local database
- Account details continue using GoCardless for real-time data
- Transaction and balance queries read from local SQLite database
- Bank management operations continue using GoCardless APIs
