feat: Implement Electric SQL replication setup for notifications table

- Added setup_electric_replication function to handle Electric SQL replication for the notifications table during app startup.
- Updated alembic migration script to remove direct SQL commands for replication, now managed in app/db.py.
- Refactored indexing functions in search_source_connectors_routes to support new start_date and end_date parameters for improved flexibility.
- Enhanced Google Gmail indexing task to utilize new date parameters, ensuring better control over indexing periods.
