  - Added allowlist validation for sorting parameters in the notebooks endpoint
  - Replaced f-string query interpolation with parameterized `$variable` binding in source chat and migration queries
  - Added defensive validation in the `get_all()` base method to prevent injection via `order_by` parameter
