abdullahnah92 a19560da41 fix(bucket-repl): persist MRF retry queue to disk and reload on startup (#3456)
* fix(bucket-repl): persist MRF retry queue to disk and reload on startup

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(bucket-repl): address three blocking MRF issues from review

1. MRF replay loses delete operations — add `MrfOpKind` discriminator to
   `MrfReplicateEntry` (Object | Delete, default=Object for backward
   compat).  `DeletedObjectReplicationInfo::to_mrf_entry` now persists
   `op=Delete`, `version_id`, `delete_marker_version_id`, and
   `delete_marker`.  `start_mrf_processor` branches on `op`: delete
   entries skip `get_object_info` and replay via
   `schedule_replication_delete` with `ReplicationType::Heal`; object
   entries follow the existing heal path.

2. `flush_mrf_to_disk` cleared the in-memory batch even on encode/write
   failure — changed return type to `bool` and callers now only
   `pending.clear()` on `true`, so a transient storage error retries
   on the next tick instead of silently dropping the batch.

3. Add focused tests: encode/decode roundtrips for object, delete-marker,
   versioned-delete, and mixed-batch entries; a routing test confirming
   op-kind propagates correctly and that the default is Object for
   legacy files; a legacy-compat test verifying old entries round-trip
   cleanly through the new format.

* style: fix clippy redundant-clone in MRF tests

Replace &[entry.clone()] with std::slice::from_ref(&entry) in two
encode_mrf_file call sites flagged by clippy's redundant_clone lint
under --all-targets --features rio-v2.

* test(bucket-repl): strengthen legacy MRF compat test with hand-built msgpack

The previous mrf_legacy_file_without_op_field_decoded_as_object test
round-tripped through encode_mrf_file, so it exercised the new format
and never touched a truly-legacy payload.

Replace it with a hand-built msgpack payload that genuinely omits the
"op", "deleteMarker", and "deleteMarkerVersionID" keys — exactly what
the old binary would have written before MrfOpKind existed.  The test
now fails if #[serde(default)] is removed from the op field, which
proves real backward compatibility rather than round-trip stability.
