Tweaks (#24484)

* fix long press on mobile in face and classification

the listener was on the image only, so long pressing on any overlaid div/text area would cause iOS to select the text instead of adding the blue outline

* improve navigation to and from explore

when viewing a tracked object in explore from a classification card, triggers, or the detail stream, explore would open and show a single tracked object. on mobile (noted especially on iOS with frigate in HA), there is no obvious way to navigate back, so add a back button in its usual spot.

also, when going back to the classification view from explore, it may not be obvious which thumbnail you were last viewing, so add a temporary blue outline around the card like review and explore already does

* test tweaks
