Robust export with progress bar, file removal persistence, copy mode

Browse Source 
- Rewrite _export_sequence with QProgressDialog, per-file error handling,
  cancel support, and continuous seq_00000 naming
- Add folder progress labels to _process_with_transitions
- Extend cleanup_old_links to remove film_temp_*.png temporaries
- Add copy-files checkbox for Docker/remote destinations
- Persist individually removed files across sessions (removed_files table)
- Recover file removals from export history for older sessions
- Save effective folder types in transition exports for reliable restore
