fix(test): harden batch_download session tests with multi-path patching + diagnostic

Full-suite runs showed test_batch_download_session_closed and
test_batch_download_closes_session_on_error failing with
"Expected close to have been called once. Called 0 times."

Changes:
- Patch SessionLocal in all possible locations: _db_mod, sys.modules,
  and function globals (if present)
- Call raw_fn directly instead of going through _call_task
- Add diagnostic assertion to verify mock_session_factory was called
- Remove try/finally restore (not needed for isolated tests)

Also includes fix from PR #1407: add missing str fields to mock clip.
