CSS link is an absolute URL breaking layout

[windware-ono]

Summary

If I run the instance on port 3000 and access it there without a reverse proxy, one of the CSS (/assets/css/lib.css) is linked as an absolute URL, which breaks the linking if the host name is not exactly specified including the port in .env for APP_URL. (ex : http://my.domain:3000/, instead of just http://my.domain/).

Steps to Reproduce

1. Install as normal.
2. node app
3. Access directly without a reverse proxy http://my.domain:3000/

This is a side effect of running Postleaf locally (it's intended to run behind a proxy such as Nginx). If you're doing local dev, the [current] requirement is to put the fully URL (including port) in your .env file.

Asset URLs could probably be changed to schemaless URLs. Aside from that, I don't see how the app could know what the proper URL should be.
