Add zoom mode functionality and refactor video feed hooks

- Implemented zoom mode in RegionSelector for digital zooming.
- Updated VideoFeedGridPainter to handle zoom interactions.
- Refactored useGetVideoFeed to support target detection and video feed queries based on mode.
- Enhanced useCreateVideoSnapshot to manage snapshots during zoom mode.
