Same drag pattern as the heap drop, but the target is the Discarded
library node. The dropped photos go to is_discarded=true via a
single bulk request.
Backend: the /photos/bulk endpoint already had a 'discard' action
branch; the missing piece was a frontend client that sent the right
shape. The previous photos.bulkUpdate sent
{ photo_ids, discard: true } against a backend that wanted
{ ids, action } — silently broken since day one. Replaced with two
narrow helpers that match BulkAction exactly: photos.bulkDiscard(ids)
and photos.bulkRestore(ids).
Frontend: LeftSidebar grows a small dnd state machine — dropTargetId
for the hovered row, isDropTarget(id) for which library nodes accept
drops, handleDrop(id, ids) for the dispatch. Today only the
'discarded' node is wired; folder rows for bulk move come next.
Drop highlight uses the reject ring/tint to match the destructive
nature of the action. Toast confirms; photos query is invalidated
so the timeline immediately drops them.
