feat(session): add session store debugging and pg_sessions table management

- Implemented a test function for the session store to verify database connection and check the existence of the pg_sessions table.
- Added logic to create the pg_sessions table if it does not exist, including defining its structure and constraints.
- Enhanced session store methods with detailed logging for session set and get operations, improving traceability and debugging capabilities.
