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
