fix(webapp): publish full realtime change records from the metadata and tags routes

A change record without tags makes the router wake every tag feed in
the environment to hydrate-and-classify, so high-frequency metadata
updates caused unnecessary database load; a record without a batchId
skips batch feeds entirely. Both routes now publish the full
membership keys, piggybacked on reads they already do.
