* fix(replication): accept a bodiless 405 as a replicated delete marker during resync
A resync verifies each delete marker with `HEAD ?versionId=<marker>` on the
target. S3 targets (RustFS, MinIO, AWS) answer that with 405 and no body,
and the SDK only synthesizes an error code for 404, so the error arrived
with `code() == None`. `is_retryable_delete_replication_head_error` then
treated it as an ambiguous failure: every delete marker counted as a failed
object with `target service error`, and a site resync over any bucket that
holds a delete marker reported the whole bucket as failed
(rustfs/backlog#2479, SITE-105 on rc.6 and nightly).
Use the raw HTTP status the way the 404 path already does: a 405 without a
code confirms the marker propagated. Ambiguous statuses still fail.
- Unit tests drive `verify_resync_head_result` against a scripted target
answering 405 (accepted) and 503 (still failed).
- e2e `test_site_replication_resync_replicates_delete_marker` joins two
sites, converges a live object and a delete marker, and requires the site
resync to complete with zero failed objects; the repl-nightly selection
digest is refreshed for the new case.
* fix(replication): verify marker-version purges by absence during resync
A delete-marker resync entry with a pending or failed version purge asks
the target to remove the marker, so the bodiless 405 that proves a
created marker propagated proves the purge did not happen. Accept the
405-as-success mapping only for marker creation (empty
version_purge_status); a purge counts as replicated only when the target
answers not found, and any other HEAD outcome stays failed. Unit tests
drive both purge statuses against the 405 fixture and the 404 fixture.
