feat(theme): AMOLED true-black rows via themedRow()

Apply listRowBackground(Color.black) per row in AMOLED mode using ThemedRowStyle
and themedRow() across Lists and Forms. Use themedList() for scroll/grouped
backgrounds. Treat segmented and clear list rows with isAMOLED-aware
listRowBackground where Color.clear was required. Removes reliance on UIKit
appearance for list cells on iOS 16+.
