Add hidden diagnostic skin toggle

- Open a hidden diagnostics dialog after tapping the header seven times within fifteen seconds. - Let the diagnostics dialog toggle the pane color/stripe skin on demand. - Restore the normal app background and pane colors by default. - Stop Scaffold from preserving the bottom navigation-bar inset while the keyboard is visible. - Apply bottom navigation padding only when the IME is not open.
