api+admin: let the curator take a photo off the landing, not just move it

Uploads still land in the community strip with consent on, by the uploader's own
tick — that default stays. What was missing is the curator's removal: the slot
select only offered the other three live placements, so "off the strip" meant
publishing the photo somewhere else or deleting the uploader's row.

`off` is a fifth slot value. The reel draws slot === 'strip' and each live slot
draws its own, so an `off` photo renders nowhere on the landing, while its owner
still has it in MY PHOTOS.
