feat(desktop): dismissable bluetooth pairing error on the page

A failed pairing showed the raw bluetoothctl output as a plain red line that
only cleared on the next attempt, and the desktop notification is suppressed
while the drawer is open, so the failure was easy to miss and impossible to
dismiss.

Show it in a red card with a close control that clears pairing.error. It has
no timeout, and clearing the source means the next identical failure shows
again rather than staying hidden.

+A failure surfaces twice. A desktop notification (`--urgency=critical`, so the
+daemon gives it no expiry) is sent regardless of where the user is, and the
+page shows the real `bluetoothctl` output in a red card. The card has no
+timeout and is dismissed by clearing `pairing.error`, so the next failure
+reappears even when the text is identical. Dismissing does not recall the
+notification.
