fix: clamp page after bulk video delete

When every video on the current page was bulk-deleted, router.refresh()
re-queried the same out-of-range page and rendered "No videos yet" even
though earlier pages still had videos. Clamp to the last valid page based
on the remaining video count, falling back to refresh in place.
