Advanced Tab

[Feature Request]
An Advanced Tab in the portal to change settings that currently require shutting down the server, going to yaml to manually modify it, restarting the server.

I understand that you might not want everyday users to access potentially disruptive settings so a flag in yaml "ShowAdvancedTab" by default set to "False" might be be a good solution.

You can add further on this by including in the yaml commented flags/variables/etc of AdguardHome system-deep modifiable factors or upcoming features that are still being tested and have no GUI yet.
An example use case of this would be the fully functional HTTP_PROXY environment variable that is still in testing/awaiting GUI programming as we speak.
