perf: evict archived/deleted photos from cache immediately

Remove archived/restored/deleted/approved UIDs from all cached photo-list
pages right after the API confirms, so the grid updates on the same tick
instead of waiting for a network round-trip. Also removes the 400ms
doneBulk animation delay (now unnecessary since tiles vanish instantly).
