fix: add minio-create-bucket local_resource to ensure bucket exists on restart

minio-post-job is a k8s Job that only runs once at install time — on minio
pod restarts the bucket is lost (no persistence) but the Job stays Complete
and never re-runs. Add an idempotent local_resource that creates the bucket
on every tilt up.
