Fix Object Lock replica reconciliation boundaries

Browse Source 
Reconcile CopyObject lock and tag revisions with the addressed destination,
including missing versions and self-referential copies. Preserve active
COMPLIANCE across pool orderings, lifecycle decisions and set-level writes.

Require retention authorization for source retention revisions, advance local
lock and tag revisions monotonically, and fail force-delete before option
parsing when bucket lock configuration cannot be read. Preserve authorized
same-content replication and existing encryption and tier cleanup behavior.
