feat: add CYD ThermoPro bridge firmware skeleton

Browse Source 
Add PlatformIO project for the ESP32-2432S028R that:
- Reads ThermoPro BLE BBQ thermometers via NimBLE-Arduino
- Exposes /api/health, /api/latest, and /api/settings HTTP endpoints
- Serves a captive-portal setup UI and touch dashboard
- Persists WiFi/BLE/settings in NVS via Preferences

Builds cleanly with pio run.
