fix: Correct roomuserid_lastnotificationread table alias

roomuserid_lastnotificationread was mapped to userroomid_highlightcount
instead of its own table, so last_notification_read() read the highlight
count and reset_notification_counts clobbered the highlight table when
setting a read marker. Add the missing table definition and fix the alias.
