Initial commit: RF Mapper v0.3.0-dev

WiFi & Bluetooth signal mapping tool for Raspberry Pi with:
- WiFi scanning via iw command
- Bluetooth Classic/BLE device discovery
- RSSI-based distance estimation
- OUI manufacturer lookup
- Web dashboard with multiple views:
  - Radar view (polar plot)
  - 2D Map (Leaflet/OpenStreetMap)
  - 3D Map (MapLibre GL JS with building extrusion)
- Floor-based device positioning
- Live BT tracking mode (auto-starts on page load)
- SQLite database for historical device tracking:
  - RSSI time-series history
  - Device statistics (avg/min/max)
  - Movement detection and velocity estimation
  - Activity patterns (hourly/daily)
  - New device alerts
  - Automatic data retention/cleanup
- REST API for all functionality
