Chris LuandClaude Opus 5.5 5150168368 s3: authorize an empty versionId as the current-object action (#12566)
* s3: authorize an empty versionId as the current-object action

GET, HEAD and DELETE treat an empty versionId as the current object, but
the action resolver keyed on the parameter's presence and authorized it
as GetObjectVersion/DeleteObjectVersion, so a Deny on GetObject or
DeleteObject did not apply.
