PR Description

Updates the apps forms for a consistent UI and improved user experience.

The forms have been rebuilt using the shadcn components that have been reduced back to their original styles, with a focus on providing consistent forms experience across the entire application.

This is a continuation made possible by #1097.

I tried to keep this limited to just the forms, but it does creep into other components slightly.. so this work continued in #1166

Should have given comments on this earlier. But I just wondered if it would be nicer when the upload SR form is in the middle of the page? Cause this page only has this form and the menu bar.

Really happy for more changes - on this one specifically, interestingly I had the same thought. The reason I didn't is the Scan Reports breadcrumb at the top, which felt suddenly in the middle of nowhere. I then figured, kind of odd to have one piece of centre aligned when nothing else is.

But yeah - I think it could work with a bit of thought
