feat: Add MinIO endpoint/public URL configuration via settings UI

Store endpointUrl and publicUrl in cloudinary_config DB table so
MinIO connection can be fully configured from the app settings
without needing environment variables.

- DB migration: adds endpoint_url and public_url columns
- Schema: adds endpointUrl/publicUrl to cloudinaryConfig table
- MinIO service: reads endpoint from DB (falls back to MINIO_ENDPOINT env)
- buildMinioUrl: accepts optional publicUrl override from DB config
- All routes updated to pass config.publicUrl to buildMinioUrl
- Settings UI (desktop + mobile): adds Endpoint URL and Public URL fields
