fixes

With these comprehensive fixes, the s3-tests should now:
✅ Return InvalidBucketState (409 Conflict) for object lock operations on invalid buckets
✅ Return InvalidRetentionPeriod for invalid retention periods
✅ Return MalformedXML for malformed retention configurations
✅ Include VersionId in response headers when available
✅ Return proper HTTP status codes for all error conditions
✅ Handle all object lock validation errors consistently
The workflow should now pass significantly more object lock tests, bringing SeaweedFS's S3 object lock implementation much closer to AWS S3 compatibility standards.
