feat(assistant): photo changes of a journal get their own card and ways back

The four new photo link tools join the journal's tools: the journey chat
offers them to editors, the trip chat loads them with the journey group and
the home chat keeps none. A journeyPhotos card shows the photos as
thumbnails with the entries they leave and reach, the first one marked as
the cover in a new order, and a caption old to new; a library add shows the
photos once they landed. A linked photo comes off again, an unlinked one
goes back, moved photos go back and a caption is written back, each while
nothing changed since. A new order of an entry's photos and a library add
have no way back yet. The journal prompt names the photo tools.
