📄 Description

Describe your changes

Added configuration options to support working with an IDP provider that has mTLS enabled.
A working example is Authentik hosted behind a mTLS nginx reverse proxy, it adds security and helps mitigate 0-days on
.

I would appreciate the addition of this feature, and perhaps expanding on it to allow netbirds own APIs to be hosted
behind a mTLS proxy.

Not being familiar with the codebase, i hope i added it to the best location for this.

Checklist

Is it a bug fix
Is a typo/documentation fix
[x ] Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
