Fix: Activate A2DP audio profile for AirPods after system reboot on Linx (#212)

Fix: Activate A2DP audio profile for AirPods after system reboot

- Add A2DP profile activation on system wake-up
- Add A2DP profile activation when BlueZ detects connection
- Add A2DP profile activation for already connected devices on startup

Fixes issue where AirPods microphone works but audio output is unavailable after reboot
