Update webapp.rb to allow for proxies

[nc-williambr]

I believe a change upstream may have changed the handling of connection restrictions.

Per this comment in ytti/oxidized, I suggest updating webapp.rb with the following line:

set :host_authorization, { permitted_hosts: [] }

This was introduced in Sinatra 4.1.0

This interesting, as the problem should occur only in a development environment.

We do not set the APP_ENV environment variable, so we get the default: development.

We run oxidized-web behind a proxy and this is a problem for us as well

Note - this does not happen with the official oxidized container, as it uses sinatra from ubuntu noble, which is Version 3.0.5.

The solution is probably to start oxidized with APP_ENV=production oxidized.
As I cannot reproduce, I cannot test it.
This Issue is being worked on in the oxidized issue 3340
