Fix storageurl in dev

[JKamsker]

Probably fixes #1683

Problem for me was, that the "download pdf" button redirected me to the right url, but the wrong port after changing the storage port in the .env file

The issue is, if you're not running in Development mode, this code block never gets accessed, and NODE_ENV is set to development only when running the app using pnpm dev.

The port is not always included in the storage URL. For example, if the storage service is running on a seperate domain/IP, on either port 80 or 443, then you wouldn't need a port. This is why I initially recommended to add the port in the STORAGE_URL env. This works no matter what environment you are running in.
