唐小鸭 dcf3e4b9e8 fix(replication): transport and persist LWW timestamps for tag, retention, and legal hold (#6129)
* test(replication): pin missing LWW timestamp header transport

Red-light tests for the replication timestamp three-header contract:

- put_object_headers_carry_replication_timestamp_headers pins that
  PutObjectOptions::header() must emit the
  x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-timestamp
  headers when the internal timestamps are set (currently missing).
- test_put_opts_from_headers_gates_replication_timestamp_persistence_on_authorization
  and test_complete_multipart_opts_persist_replication_timestamps_when_authorized
  pin that an authorized replication PUT / multipart complete must persist
  the inbound timestamps into the internal metadata keys while unauthorized
  requests must not (currently never persisted).
- fake_s3_target journals the three timestamp headers per request
  (ReplicationTimestampHeaders on RequestRecord) so sender-side e2e
  assertions can observe what a real target receives; self-test included.

* fix(replication): transport and persist LWW timestamps for tag, retention, and legal hold

Active-active conflict resolution for concurrent tag/retention/legal-hold
edits needs the source's per-category modification times on both sides of
the wire; the three AdvancedPutOptions timestamp fields were dead and the
headers were neither sent nor parsed.

- Emit x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-
  timestamp from PutObjectOptions::header(); names and RFC3339 values
  interoperate with MinIO (minio-go constants.go, object-api-options.go),
  pinned by a header_compat wire-name test.
- Default the three AdvancedPutOptions timestamps to UNIX_EPOCH and skip
  epoch values in header(), so "never modified" is not sent as a
  modification made now.
- Parse the headers only on authorized replication PUTs and multipart
  completes, expose them as Option<OffsetDateTime> on ObjectOptions, and
  persist them into the dual-prefix internal metadata keys so the
  outbound pass (replication_target_boundary) reads the source's
  timestamps instead of the mod_time fallback.
- Record the local tagging timestamp in the PutObjectTagging and
  DeleteObjectTagging eval metadata, mirroring the object-lock handlers;
  without it the sender only ever had the mod_time fallback to offer.

Receiver-side LWW comparison (keep newer stored category metadata over a
stale inbound copy) is left as a TODO at the parse site.

* fix(replication): load the stored tagging timestamp independently of remaining tags

Review: DeleteObjectTagging persists the tagging-timestamp internal key
but leaves the object tagless, and the outbound mapper only loaded the
key inside the user_tags-nonempty branch — the deletion's LWW timestamp
stayed at the epoch and the header was omitted, so the deletion could
never win conflict resolution on the replica. The stored key is now
loaded unconditionally; the mod_time fallback still applies only while
tags exist (MinIO parity), and a tagless object without the key keeps
the epoch default (no header). Deletion-path regression test added.

* fix(storage): reserve replication transport names at metadata ingest

Second review round: a client PUT of
x-amz-meta-x-rustfs-source-replication-tagging-timestamp materialized
the bare transport key as stored user metadata. The outbound
replication header builder forwards user metadata verbatim on a
server-authorized request, so the receiver would persist the
attacker-chosen value as trusted internal LWW state — and for a
tagless object nothing later overwrites it.

The ingest namespacing guard now reserves the whole
x-rustfs-source- / x-minio-source- families (the new timestamps and
their siblings: source-mtime/-etag/-version-id/-replication-request),
folding forged keys back under x-amz-meta-. Forged-ingress regression
covers both prefixes and a sibling.

* fix(replication): harden timestamp replay

* fix(app): route retention helper through facade
