TabBarIcon, ScreenContent, HeaderButton, EditScreenInfo, Container, RN Button, BackButton, two, all using StyleSheet.create rather than utilizing nativewind/tailwindcss styles. Suggest moving all styles to tailwindcss and removing SyleSheet usage entirely.

_layout.tsx is using hardcoded black color for the selected tab font color, which doesnt look good in Dark Mode. Suggest using useColorScheme foreground text color (Black in Light Mode, White in Dark Mode).

I have already fixed these all in my local and will be submitting a pull request to clean these up later today after my vampiric sleep cycle.
