* test: align vector bucket policy coverage with vector actions
* s3vectors: validate ARN service and resource shape before resolving indexes
* test: exercise signed vector bucket policies and catalog lifecycle
* ci: require the expanded vector integration matrix and all gateway tests
* test: reject index ARNs in bucket-level API requests
* s3vectors: scope ARN resolution to the gateway namespace
* s3vectors: reject name fields that conflict with resolved ARNs
bucketARNs and resolveIndexARNs already reject an indexArn that names a
different bucket than vectorBucketArn, but a vectorBucketName or
indexName disagreeing with the ARNs was silently dropped. Validate the
plain names against the resolved ARN values the same way.
* test: cover conflicting vector names and ARNs in live requests
