Add UUID filter for BLE scanner

Frontend:
- Add uuid_filter_hex field to BLE scanner config section
- Add translations for UUID filter (en/ru)
- Field accepts 32 hex characters (iBeacon UUID format)
- Optional field - when set, only beacons matching UUID are reported

Backend:
- Add uuid_filter_hex to default config response
- Add upload_endpoint fields to default config for BLE/WiFi

Usage:
Admin enables UUID filter in device settings, device receives
config via polling (≤30 sec) and filters beacons by UUID.
