don't use S3 CreateBucket and clean up

Pass S3_REGION and S3_PUBLIC_USE_SSL through compose, treat blank public
SSL as unset, and skip CreateBucket when IAM only allows access to an
existing bucket.

-- Local development defaults to **SeaweedFS** (S3-compatible) via Docker Compose.
+- Local development defaults to **SeaweedFS** (S3-compatible) via Docker Compose. Compose runs an `s3-init` step that creates the dev bucket before the server starts.
 - Production can use any S3-compatible provider; **AWS S3** is the expected choice.
 - The Python server uses the `minio` Python SDK against the S3 API.
 - Runtime configuration uses `S3_*` environment variables.

 Use your bucket's regional hostname for both endpoints unless you deliberately split internal vs client-facing access. `S3_PUBLIC_ENDPOINT` must be reachable by whatever uploads and downloads via presigned URLs (clients, not just the server).
 
-On startup the server calls `CreateBucket` if the bucket is missing. In AWS it is simpler to **pre-create the bucket** and grant object permissions only (see IAM below).
