Rider proof-of-delivery / signature photos need a way to reach storage.
The legacy (jupiter) rider app shipped the DigitalOcean Spaces access/secret
key inside the Flutter build and PUT to the bucket directly. This moves the
key server-side and hands the app a short-lived presigned PUT URL instead.
- internal/storage/spaces.go: self-contained AWS SigV4 query presigner for
Spaces (S3 API) — no aws-sdk-go-v2 dependency for a single presign op.
Verified live end-to-end (presign -> PUT 200 -> CDN GET matches).
- controllers/uploadController.go: POST /miler/uploads/sign returns
{ uploadurl, url, method, headers, key, expiresin }. Same bucket/folders/
CDN (images.nearle.app) as jupiter so images share one store.
- Reads DO_SPACES_* from .env via godotenv; returns 503 UPLOAD_NOT_CONFIGURED
when unset rather than handing out URLs that 403.
