WIP: enchance device pairing process

- Introduced devicePasswordProtected signal in AppContext to notify when a device is password protected.
- Modified DeviceManagerWidget to handle devicePasswordProtected signal and update pending device state accordingly.
- Enhanced DevicePendingWidget to display appropriate messages based on device lock status.
