Admin/Public: refine topics workflow and gallery topic nav

Browse Source 
Switch topic editing in admin to autosave-on-change with tree-based controls where parent selection is create-only and delete remains explicit. Add public sidebar navigation by topics with sort-index ordering, preserve topic context in photo navigation/comments, and show stable AI/comment badges on catalog cards.
