fix(storage): stop deleting covers, place images and journey photos another row may still show

Replacing a trip or list cover, changing or deleting a place or saved-place
image and deleting a journey photo removed the bytes at once, without asking
whether a trip copy, a journey, a saved place or another photo row still
named them (#2924). Those paths now leave the object in place and the reclaim
job removes it once no row names it. A journey photo the user deletes takes
its local photo row with it when nothing else links it, so its bytes become
reclaimable instead of being kept by a row nobody sees.

A place image copied from a trip file is still dropped at once when the
update that would name it fails: that copy was never anyone else's.

Size and warning baselines follow the shrunk files.
