### Added

- **Pause / Resume** button to temporarily halt decryption
- **Stop** button to cancel decryption mid-process
- **Real-time log output** with color-coded levels (INFO=green, WARNING=yellow, ERROR=red, DEBUG=gray)

- **Progress status** — shows current phase and folder being processed
- **Browse dialogs** for backup and destination folders
- **Show/hide password** toggle
- **Select All / Deselect All** for folder selection
