Subject: [PATCH] fix(mobile): show Refresh thumbnail only when preview missing
 or broken

The Refresh thumbnail button appeared on every scene, which is noise for the majority
that already have a good preview (report 26c114ed). Show it only when no source has a
usable thumbnail or the only thumbnails are rotting (sxyprn/trafficdeposit), which is
exactly when a manual refresh helps (the original d3376a71 case).
