fix(tests): add missing mock settings attrs in test_original_filename_preservation

The test was patching `settings` with a MagicMock but only setting
`workdir`.  Other attributes (`default_owner_id`, `enable_deduplication`,
`show_deduplication_step`, `enable_text_quality_check`) remained as
MagicMock objects.  When `default_owner_id` (truthy MagicMock) was
assigned to `owner_id` and passed to SQLAlchemy, SQLite rejected the
unsupported type.

Fix: explicitly set all accessed settings attributes to sensible test
defaults in both test functions.
