Zhengchao An 5e73d59eb6 fix(replication): re-derive replication decision when replaying MRF delete entries (backlog#858) (#4315)
MRF delete replay reconstructed the delete with `..Default::default()`, leaving
`replication_state = None`. `replicate_delete` derives its target set purely
from `replication_state.replicate_decision_str`, so an empty state produced an
empty decision -> zero targets: the replayed delete contacted no remote at all,
a silent no-op that left replicas permanently diverged after a restart.

The MRF entry doesn't persist the decision and the source object is already
gone, so re-derive it from the live bucket config at replay time via
`check_replicate_delete` — mirroring the object heal path
(`get_heal_replicate_object_info`) — and set it on the reconstructed delete's
`replication_state`. This is a contained fix with no change to the on-disk MRF
format.

Refs backlog#799 (B9).

Note: the source delete-marker mtime is still not persisted in the MRF entry,
so a replayed delete marker is stamped with the replay time on the target. That
is a separate, minor consistency nuance (the delete now propagates correctly)
and can be addressed by extending the MRF entry format in a follow-up.
