fix: multiple improvements and CI/CD updates

Frontend fixes:
- Add missing translations for chunk upload (upload.uploadingChunks, common.chunk)
- Fix photo deletion visual bug by tracking deletion state per photo
- Prevent UI confusion when deleting photos in admin grid

Backend fixes:
- Add file existence checks before deleting thumbnails
- Prevent ENOENT errors for missing thumbnail files
- Improve error handling in photo deletion

CI/CD updates:
- Remove Gitea release creation from Drone pipeline
- Simplify GitHub mirror workflow (remove history rewriting, keep file removal)
- Add clean-git-history.sh script for manual history cleanup

These changes improve the admin photo management experience and streamline
the CI/CD process for better maintainability.
