feat(webapp): Make API_URL changeable and improve README

[andreasnuesslein]

The API_URL needs to be set via the environment now. It should automatically be set by docker-compose.yml for the default scenario.

See #397

Thanks for this new PR, @andreasnuesslein!

In the code changes, VUE_APP_API_BASE_URL sometimes seems to refer to the full URL (https://desec.io/api/v1/), and sometimes just to the path (/api/v1/). It seems to me something is off - or am I misunderstanding?

Thanks, @andreasnuesslein. Enabling contributors to circumvent the whole docker setup is a really good idea!

I have a couple of suggestions:

1. Persist the .env file in the repo -- I confirmed it will not interfere with the docker-setup
2. Add the remaining env variables to webapp/.env to fix some missing email addresses and the like in the webapp. I tried locally

   VUE_APP_API_BASE_URL = "https://desec.io/api/v1/"
   VUE_APP_DESECSTACK_DOMAIN=io
   VUE_APP_DESECSTACK_NS=ns1.desec.io ns2.desec.org
   VUE_APP_DESECSTACK_API_SEPA_CREDITOR_ID=FOOBAR
   VUE_APP_DESECSTACK_API_SEPA_CREDITOR_NAME=FOOBAR
   VUE_APP_LOCAL_PUBLIC_SUFFIXES=dedyn.io
   [email protected]
   

   Maybe add a note in docker-compose.yml that extending the list of environment variables requires changes to webapp/.env.
3. Introduce an additional env variable, e.g. VUE_APP_NO_DOCKER=1 that automatically switches the hot reload backend (or switch depending on API_BASE_URL). (Using the wrong hot reload backend gives misleading error messages in the browsers console.)

cough cough yeah I know :( I've been crazy swamped and I still kind of am at the moment. I still want to help and I hope better days will come. - Sadly that's all that I can offer at this moment.
