feat: add device UUID pairing — unique identity per ESP-phone pair

Browse source 
- Firmware: auto-generate 16-byte UUID on first boot (NVS), new READ characteristic
- BLE name: AtomS3R-Relay → SylDa_Server
- KEY? now returns DEVICE_ID + HMAC_KEY, SET_ID command for UUID provisioning
- App: UUID+HMAC loaded from prefs, scan by service UUID, verify UUID after connect
- UUID mismatch → disconnect + skip address + rescan
- Key conflict dialog: keep ESP keys, overwrite ESP (with checkbox confirm), or cancel
- NO_KEY with existing app keys: send existing pair instead of generating new
- Added design spec doc
