Replace the presigned-URL redirect (302) in GET /api/v1/images/{id}/file
with a direct proxy that fetches bytes from S3 server-side and returns them
to the client. The browser never contacts the storage backend, eliminating
the /etc/hosts workaround needed in local development.
- StorageBackend: swap get_presigned_url for get(key) -> bytes
- S3StorageBackend: implement get() via aiobotocore get_object
- serve_image_file: return Response with ETag + Cache-Control: immutable
- test_serving: assert 200 + content-type + ETag; add no-storage-details test
- Spec Kit artifacts for feature 002-api-image-proxy
