feat: Android BLE pairing UI for UWB tag (Issue #700)
- UwbTagBleActivity: BLE scan filtered to 'UWB_TAG_XXXX' device names - Connects to GATT service 12345678-1234-5678-1234-56789abcdef0 - Read/write JSON config char: sleep_timeout_s, display_brightness, tag_name, uwb_channel, ranging_interval_ms, battery_report - Subscribes to status + battery notification characteristics - Material Design UI with scan list, config form, and live status - Runtime BLE permission handling for API 26+ / API 31+ Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
