Add a setting to override the hostname per docker connection

[tylerdurden4285]

Description

Currently the user is forced to manually update the external address for every single app that is added to homarr because it defaults to localhost. Since not all users access their homarr directly from their localhost and some use tools like tailscale then it only works with the following approach by using [homarr_base] dynamic variable

Ideally there would be a field in settings where the user could select to toggle between this default of:

a. localhost (current only option)
b. [homarr_base]

That way when a new app is added it will just work without any pointless need to manually type the text in each time. Considering that the main point of homarr is to add the docker apps to the dashboard, and some people have 10's or 100's of apps then this seems like a big problem to solve.

Priority

Medium (Would be very useful)
