fix(replication): harden backlog observability (#5564)

Browse Source 
Add RAII guards for replication runtime backlog tickets so active worker and queue counters unwind on every terminal path.

Expose node-local MRF pending, dropped, missed, and flush-failure metrics through the bucket replication Prometheus collector while keeping the existing current backlog and durable MRF gauges additive.

Update durable MRF summary maintenance to aggregate incrementally during the persister loop, avoiding repeated full-entry scans on each successful flush.
