fix(ente): add MinIO object storage for photo uploads

Museum requires an S3-compatible object storage backend for file
uploads. The install script had dummy S3 credentials pointing to
localhost:3200 but no service was running there, causing HTTP 500
on /files/upload-url.

- Install MinIO binary with random password
- Create required buckets (b2-eu-cen, wasabi-eu-central-2-v3, scw-eu-fr-v3)
- Configure museum.yaml with proper S3 credentials and bucket names
- MinIO runs on port 3200 (API) and 3201 (console)
