Refactor database access to use a unified dbAdapter for SQLite and PostgreSQL

- Replaced direct database calls with dbAdapter methods in fieldRoutes, itemRoutes, listRoutes, syncRoutes, and webRoutes.
- Implemented a new db.ts file to handle database interactions for both SQLite and PostgreSQL.
- Added WebSocket support for real-time synchronization in WebSocketSyncClient and ws.ts.
- Updated TypeScript configuration to include WebSocket types.
- Created a new WebSocket server for handling sync requests and responses.
- Ensured compatibility with both SQLite and PostgreSQL by using parameterized queries.
