Support Comfyui backends with authentification such as ComfyUI-Login

[RubenGarcia]

Feature Idea

I would like an auth field when configuring a comfyui instance to add e.g. a Bearer token so instances with Login node can be used.
Something similar to

Generally you should set up the login layer in Swarm, or in front of Swarm, not in between swarm and the backend. Swarm should directly control the backend in most cases.

I have a usecase where the backend is setup like this.

If I patch SwarmUI with the required functionality, would you consider merging my changes?
