fix: Replace placeholder BLE UUIDs with Reticulum standard UUIDs

Browse source 
Fixed discovery failure caused by GATT server advertising wrong service UUIDs.

Root cause: BLEGATTServer and BLEInterface were using placeholder/test UUIDs
(00000001-5824-4f48-9e1a-3b3e8f0c1234 etc.) instead of the Reticulum standard
UUID namespace (37145b00-442d-4a94-917f-8f42c5da28e*).

This caused Pis to advertise services that scanners couldn't recognize,
blocking all BLE discovery and connection attempts.

Changes:
- BLEGATTServer.py: Updated all 4 service/characteristic UUIDs
- BLEInterface.py: Updated all 4 service/characteristic UUIDs

Diagnosed using nRF Connect mobile app which showed wrong UUIDs being advertised.
