Add mobile foundation: iOS zoom fix, safe area insets, row padding

- Input base font 16px on mobile to prevent iOS Safari auto-zoom
- Safe area insets for notched phones (top/bottom bars)
- viewport-fit=cover to enable safe area env() values
- Action bar flex-wrap for custom stat field overflow
- Slightly increased row padding on mobile (py-3 sm:py-2)
- Removed redundant font-size classes from Input usages
