Needs a better way to route all http/https traffic through mitmproxy

Problem Description

I have been spending 3+ hours on trying to route all traffic on the system through mitmproxy. Wireguard and mitmproxy -local do not do it because they use DNS which cannot be edited.

There needs to be a one-click gui to do this, likely in mitmweb, just give the sudo password and it does the rest.

Instead I've spend 3+ hours of my life trying to get this to work battling everything from esoteric iptables commands that didn't work, TLS errors, broken prompts from some of the worst AI systems in history (Gemini and Deepseek) and still no result.

This is an extremely essential basic feature of any proxy, because without it it's impossible to intercept app data, it is also just nice to be able to host mitmproxy, connect your machine to it and inspect/edit any packet on your system for the freedom of doing so.
