Suggestion: Replace Google STUN Server & Add Customization Option

[kryptografisch]

Hi,

First off, thank you for this fantastic software! ❤️ I truly appreciate the WebRTC-based approach to enhancing user privacy.

From a privacy perspective, I recommend avoiding the use of the Google STUN server as the default option. While I haven't yet researched alternative STUN servers, I'd be happy to contribute in exploring and testing potential options.

Additionally, it would be great to have a way to customize the STUN server address. For example:

Provide an environment variable (for Docker or the web server) to specify the STUN server.
Enable nginx to dynamically replace the STUN server address, which could be based on the value of the environment variable.

Alternatively, a compile-time configuration step for the web resources could be considered. I’m open to other ideas if there’s a better approach!

Let me know how I can assist, and thanks again for your amazing work!
