Zhengchao An 68f048b8fe fix(replication): persist delete marker mtime in MRF entries (#4331)
fix(replication): persist original mtime in MRF entries (backlog#867)

MRF delete entries did not persist the original delete-marker mtime, so
after a restart the recovery replay path reconstructed the delete without
a source timestamp. Downstream the replica delete-marker was stamped with
the replay time (now()) instead of the source mtime, causing delete-marker
timestamp divergence across clusters.

Extend the MrfReplicateEntry disk format with an optional deleteMarkerMtime
field (persisted as Unix nanoseconds) in both duplicate struct definitions
(rustfs-replication and rustfs-filemeta). DeletedObjectReplicationInfo now
persists delete_marker_mtime, and start_mrf_processor restores it onto the
reconstructed delete so the replica keeps the source timestamp.

Backward compatibility: the new key uses skip_serializing_if + serde
default, so historical MRF files without it decode to None and replay
falls back to the current time (pre-#867 behaviour). No panic or entry
loss on old files.

Closes rustfs/backlog#867
