Add a "Delete device pairings" button below the list of connections. When clicking on it, pop up a confirmation popover, asking for confirmation. When confirmed, call the UltimateHackingKeyboard/firmware#1082 command.

After deleting the pairings, don't delete the affected host connections but add a https://fontawesome.com/icons/circle-exclamation?f=sharp&s=solid icon in their rightmost columns. When hovering over this icon, display a tooltip with the following content:

"This connection has been unpaired. You can re-pair this device."

@kareltucek How to query the paired/unpaired states of the host connections?
