Merge visual UI and form-base UI into one

[depatchedmode]

Things the form-based UI is missing:

• 1. Image upload - we'll refactor the ui to add a "convert to base64 image" helper
• 2. Image previews - for output previews in general, we'll make those visible as a expandable area at the bottom of each function Moved to Result pane instead
• 3. Task status: ready, from cache, running or completed status after hitting run
• 4. Run history: let's lose it for now and revive it in a future release. It's super helpful to have once you are running a stable workflow, but we ain't there yet.

Let's make the above changes.

@depatchedmode for point number 2, I'm thinking I should just add some cards to the big open Result pane instead. It's got a lot of unused real estate right now and it would probably make sense for the user to look there to inspect the results instead. what do you think?

@depatchedmode this is what i ended up going with

happy to chat through potential alternatives

@avivash That looks great! We can tweak later. I think it communicates clearly. The only things I'd do:

1. Give the final output position:sticky to the bottom.
2. Give it a label. "Final Output"? Just to indicate it's the end of the workflow.
