houseme fbec33bd29 Expose target-scoped durable MRF backlog metrics (#5584)
* feat(replication): expose target durable mrf backlog

Add target ARN attribution to durable MRF entries and surface target-scoped durable backlog metrics without changing existing bucket-only metric labels.

Keep legacy MRF files bucket-only by defaulting missing targetARNs to an empty list, and expose target snapshots through an additive API so existing DurableMrfBacklogSummary callers remain source-compatible.

* feat(replication): expose runtime target backlog (#5586)

Track runtime replication backlog by target ARN for regular, large, delete, and MRF admission paths while preserving the existing bucket-level backlog semantics.

Add target-scoped current backlog metrics and merge them with durable target backlog snapshots for observability.
