fix(catch-records): stop bulk upserts clobbering fields a toggle never touched

Toggling one checkbox sent the whole record, so a stale copy of the other fields
could overwrite newer values. Send only the fields that changed, group rows by
the columns they carry, and upsert each group with defaultToNull: false so
omitted columns keep their stored value. Results are returned in the caller's
order rather than whatever order the groups came back in.
