Add more Bluetooth debugging and disable scan duty cycling

- Add better state descriptions for both central and peripheral managers
- Add logging when setting up peripheral and adding service
- Temporarily disable scan duty cycling to ensure continuous scanning
- Add service UUID logging during peripheral setup

This should help identify:
1. Why Mac shows 'unsupported' state for Bluetooth
2. Whether services are being added successfully
3. If advertising is actually starting
