   ### Summary
   
   This PR makes `FabAirflowSecurityManagerOverride.load_user` more robust by:
   
   - Safely handling cases where the user does not exist or is inactive.
   - Catching database exceptions (including `PendingRollbackError`), rolling back the session, and returning `None` instead of letting the exception bubble up.
   
   The goal is to prevent `sqlalchemy.exc.PendingRollbackError` from causing `500 Internal Server Error` responses on the web UI when loading the current user.
