fix(ui): split ViewBuilders for Swift 5.7 ten-child limit (#146)

Actions run 33666 (Xcode 14.2, macOS 12) failed to compile: the
sidebar VStack had 14 children and SaveMediaRecipeDialog had 13,
over the Swift 5.7 ViewBuilder 10-child cap. Extracted
layout-transparent Group subviews (header/presetBlock/mediaBlock/
studioButtons/stepperAndProject; fields/readOnlyRows) — no id,
order, or layout change.
