Tile: Show an applying hint while a policy write settles

The QS tile's subtitle covered the plug-latched replug hint but not the
ordinary settling window - a policy tapped elsewhere read as already
final when QS was opened mid-transition. The subtitle now prefers the
two pending states (mutually exclusive by construction) over the static
access/adapter label, with the same QS-open staleness the replug hint
already accepts.
