Jerry Yan f5cb265667 feat(annotation): implement file version management for annotation feature

Add support for detecting new file versions and switching to them:

Backend Changes:
- Add file_version column to AnnotationResult model
- Create Alembic migration for database schema update
- Implement check_file_version() method to compare annotation and file versions
- Implement use_new_version() method to clear annotations and update version
- Update upsert_annotation() to record file version when saving
- Add new API endpoints: GET /version and POST /use-new-version
- Add FileVersionCheckResponse and UseNewVersionResponse schemas

Frontend Changes:
- Add checkFileVersionUsingGet and useNewVersionUsingPost API calls
- Add version warning banner showing current vs latest file version
- Add 'Use New Version' button with confirmation dialog
- Clear version info state when switching files to avoid stale warnings

Bug Fixes:
- Fix previousFileVersion returning updated value (save before update)
- Handle null file_version for historical data compatibility
- Fix segmented annotation clearing (preserve structure, clear results)
- Fix files without annotations incorrectly showing new version warnings
- Preserve total_segments when clearing segmented annotations
