fix(heal): emit MRF repair notices on completion (#6309)

Browse Source 
Move MRF repaired-event fan-out from admission to successful terminal completion so scanner pending-heal ledgers only clear after the canonical heal task actually finishes. Track notice ownership across duplicate admission, retry merge, cancellation, and queue displacement.
