Admin Console not showing under circumstances

Describe the bug

Using different http/https and proxy configurations is easy enough to end up with the Admin UI not working and staying in a page reload infinite loop.

Me and @vmuzikar narrowed down the issue to an incorrect variable value (namely authServerUrl) being injected into an “in-page” javascript block:

<script type="[text/javascript]()">
        var authServerUrl = 'https://localhost';
        var authUrl = 'http://localhost:8080';
        var consoleBaseUrl = '/admin/master/console/';
        var resourceUrl = '/resources/xa1ud/admin/keycloak';
        var masterRealm = 'master';
        var resourceVersion = 'xa1ud';
</script>

The problem shows up in various situations:

export KC_DB=dev-mem
export KC_HOSTNAME=localhost
export KC_HTTP_ENABLED=true

./bin/kc.sh start --auto-build

or even:

./bin/kc.sh start --auto-build --hostname="localhost" --proxy=edge

and again:

./bin/kc.sh start-dev --hostname="localhost" --proxy=edge

The problem shows up in three parts, the protocol (HTTP vs. HTTPS), the hostname mangling, and the associated port.
