4bdbfbaaa8 s3tables: judge an absent tag target by its canonical ARN (#11912)
* s3tables: judge an absent tag target by its canonical ARN

authorizeAbsentTarget matched the bucket policy's Deny statements
against the request's raw resource ARN. The ARN parsers accept any
account and region but resolve the target by name, so a caller with an
identity grant could reformat the ARN, miss the Deny match, and learn
whether a denied name exists — the oracle the absent-target check was
meant to close. Rebuild the ARN from the resolved names and the real
bucket owner and evaluate the Deny against that, matching what the
existing-target path checks.

* s3tables: keep the absent-target deny check behind a supplied ARN

Callers that pass no resource ARN (ListTables, ListViews,
CreateNamespace) must reach CheckTableOrBucketPermission's admin
shortcut unchanged; running the bucket-policy Deny match first would
deny the admin lists those callers take.
