- Fix "cannot convert 'str' object to bytes" error in BLE identity engine
by adding robust _convert_to_bytes() helper that handles bytes, hex
strings, bytearrays, and arrays
- Improve DBus scanner to safely handle various data types for
manufacturer_data and service_data with proper error handling
- Add monitor mode interface detection in WiFi scanner to provide clear
error message when quick scan is attempted on monitor mode interface

- New device_identity.py: Clusters BLE/WiFi observations into probable
physical devices using passive fingerprinting (not MAC addresses)
- Fingerprinting based on manufacturer data, service UUIDs, capabilities,
timing patterns, and RSSI trajectories
- Session tracking with automatic gap detection
- Risk indicators: stable RSSI, MAC rotation, ESP32 chipsets, audio-capable
- Full audit trail for all clustering decisions
- New ble_scanner.py: Cross-platform BLE scanning with bleak library
- Detects AirTags, Tile, SmartTags, ESP32 by manufacturer ID
- Fallback to system tools (btmgmt, hcitool, system_profiler)
- Added API endpoints for device identity clustering (/tscm/identity/*)
- Updated setup.sh with bleak dependency
- Updated documentation with TSCM features and hardware requirements
