The query said `SET view_settings = $2, updated_at = NOW()` but the
collections table has never had an updated_at column — every call
failed with 42703. The one caller (media_scanner's series-import
provenance write) discards the error, so the failure was silent:
imported-from-series view settings never persisted. Surfaced while
writing the sibling UpdateCollectionMatchMode query for item 2.4 (the
item-2.4 commit message prematurely claimed this fix — this is that
fix, for real).
