Propagate port settings

[mcmidget]

Hi,

I've just setup fusio on a development machine and I spotted the port setting is not propagated along config files. This lead to be unable to login via webui because the port setting was not correctly set at public/apps/fusio/index.html

        fusioProvider.setBaseUrl('https://api.example.com:**MISSING-PORT**/api/index.php/');

Also port setting wasn't present at .env file

Hi, so you can add the port to the FUSIO_HOST env, then this should be also added correctly to the apps s. https://github.com/apioo/fusio-docker/blob/main/docker-compose.yml#L10
