test: MinIO integration tests for bucket provisioner + graceful degradation fixes

+/**
+ * Integration tests for BucketProvisioner against a real MinIO instance.
+ *
+ * These tests exercise the full provisioning pipeline end-to-end:
+ *   1. provision() — create bucket, set policies, CORS, versioning, lifecycle
+ *   2. inspect() — read back all bucket config and verify it matches
+ *   3. updateCors() — change CORS rules on an existing bucket
+ *   4. bucketExists() — verify bucket existence checks
+ *
+ * Requires MinIO running on localhost:9000 (docker-compose or CI service).
+ * Skips gracefully when MinIO is not reachable.
+ *
+ * NOTE: MinIO free / edge-cicd does NOT support several S3 APIs:
+ *   - PutBucketCors / GetBucketCors (paid AIStor feature)
+ *   - PutPublicAccessBlock / GetPublicAccessBlock
+ *   - PutBucketPolicy (may partially work)
+ * The provisioner gracefully degrades for non-AWS providers, so provision()
+ * and updateCors() succeed but CORS/policy/publicAccessBlock are not applied.
+ * Tests verify the graceful degradation path and focus on APIs MinIO supports:
+ * bucket creation and bucket existence checks.
+ * Versioning, lifecycle, CORS, policies, and public access block all gracefully
+ * degrade (provision() succeeds but the feature is not applied on MinIO).
