Remove all debug prints and fix API misuse warnings

- Remove [PEERS] and [ANNOUNCE] debug print statements
- Fix unused variable warnings in BluetoothMeshService
- Add peripheral.state == .connected check before writeValue in announce sending
- Remove unused peerInfo and peerNicknamesCopy variables
- Fix API MISUSE warnings about sending commands to disconnected peripherals
