Bluetooth and Wi-Fi improvements (#622)

- Enable BT by default in DTS, and create separate radio on/of functionality (like recent Wi-Fi changes)
- Bluetooth event handling now uses queued subscriptions, improving event delivery and application responsiveness.
- Improved synchronization of Bluetooth advertising, connections, HID, MIDI, and SPP operations.
- Enhanced cleanup during Bluetooth shutdown and subscription removal.
- Clarified Bluetooth start and stop behavior.
- Improved wifi driver subscription stability to prevent endless loops
