Enhance Bluetooth functionality and GUI integration

Browse Source 
- Add Bluetooth device list management with discovery and pairing support
- Implement volume control with AVRC integration
- Add system event handling for GUI-to-Bluetooth communication
- Enhance menu system with device selection and volume control pages
- Improve memory management by making menu creation lazy
- Add proper event subscription between GUI and Bluetooth modules
- Update filter coefficient for improved audio clicking behavior
