Queue functionality in the Inference panel

[Ivan-Malinovski]

Proposal

I really like the simplicity of the inference panel in Stability Matrix, but it's lacking one big QOL feature: queues.

I sometimes want to try out a bunch of small changes in a row, but now I have to keep an eye on it, and start a new generation every time a picture is done.

I'd like there to be a "queue" button, so that current prompt just starts generating when the previous one is done.

This is already a feature in ComfyUI, so I suppose it should be doable.
