Changelog Entry

Description

added Stable Diffusion 3 support alongside ComfyUI configuration.

Fixed

closes #1459 alongside addressing the top comment (for ComfyUI only, as I do not have an AUTOMATIC1111 setup to test with). also closes #1958 (again, for ComfyUI only, since afaik AUTOMATIC1111 doesn't even support SD3).

Security

N/A

Breaking Changes

No breaking changes, because if the environment variable does not exist, we fall back to the original behavior.

Additional Information

All three of the changes I wrote in the past few hours are built together in the Docker image ghcr.io/johnthenerd/open-webui:comfyui-test3 and I am currently running them in my homelab without any issues. Tested with and without the new environment variables.
