feat: implement ofxpimapper-full-stack

- Unified setup script with OpenFrameworks and ofxPiMapper installation.
- Integrated C++ source modification for 'Highlight Surface' OSC listener.
- Full-featured 5-tab React/Tailwind web UI (Dashboard, Mapping, Media, Network, System).
- WebSocket-based real-time vertex/surface manipulation and throttled log streaming.
- Media Vault with ffprobe validation (H.264) and Mapping Manifest persistence.
- Hybrid Networking UI with WiFi scanning, connection, and AP configuration.
- System control endpoints for Reboot, Shutdown, and Mapping Save.
