revert evictFromCache, add back delay + marks invalidation

Remove evictFromCache entirely - the cache-manipulation approach was
brittle and broke both archive (photos not removed) and tags
(colors/ratings showing empty). Replace with: 200ms delay before
invalidation to let PhotoPrism's indexer process the change, plus
invalidateQueries(['marks']) so tag caches (colors, ratings, notes)
refresh alongside the photo timeline.
