feat: enhance boxing module with box mode support and fix Android build

- Add box_mode parameter to box submission API for one-to-one/one-to-many/many-to-one modes
- Allow re-scan override in one2one mode without clearing state
- Improve duplicate detection messages per boxing mode
- Disable Kotlin incremental compilation to fix cross-drive build failure
