feat(desktop): bluetooth module, tile and page

Native Quickshell.Bluetooth for adapter power, discoverable, scan,
connect, disconnect, trust and forget. Pairing is separate, because
quickshell ships no BlueZ agent.

The adapter is null for the first ~2s, so every access is navigated
safely rather than assuming a first paint.
