Zhengchao An 650a3e5734 fix(replication): classify resync verification HEAD errors instead of miscounting (backlog#862) (#4312)
The resync result verification HEADed the target after replicating and counted
the outcome with inverted error handling:

- for a delete marker, ANY HEAD error (timeout, 5xx, auth, malformed) was
  counted as replicated (success);
- for a versioned object against an AWS-style target, HEAD was sent with the
  RustFS UUID versionId, which AWS rejects with 400, so a well-replicated
  object was counted as failed.

Classify the error before counting:

- delete marker: only a definitive 404/NoSuchKey or 405/MethodNotAllowed
  confirms the marker propagated (`is_retryable_delete_replication_head_error`
  == false); any retryable/ambiguous error now counts as failed;
- versioned object with a version-id-format rejection: re-verify via
  `head_object_fallback` (versionId-less HEAD) before deciding — present ->
  replicated, absent/error -> failed;
- all other errors: failed, as before.

Reuses the existing, unit-tested classifier helpers. Verified against the
existing resyncer suite (24 tests).
