fix:[#875] move output behind button

[jardon]

The PR hides the output of the command until the user presses, "view output". this allows a cleaner interface and also enables the action pop up to have a dedicated view for the output so that the viewbox can be bigger. here are some sample screen shots:

closes #875

i was able to get what im wanting with a debugger, but i havent been able to implement it yet in code. i set the toplevel_box valign to fill and it looks like whats shown below

i ended up just making the output box a height of 220. i dont like it, but the parent PdsActionPage is already fixed at 450 so this works.

open to suggestions if someone knows a better way

Thanks for the PR.

I suggest showing the output button from the beginning. Otherwise, it would be hard to track the progress for long-running tasks like pulling images.

i reworked this to make it visible from the start.

i also swapped the button order as when the pop up changed state, the view button would move causing misclicks
