fix: force default light mode for public pages and admin

- Set defaultColorScheme='light' in root MantineProvider
- Change darkModeStore default from system preference to false (light)
- Add MantineProvider with light theme to darmasaba/layout.tsx
- Remove dark mode dependency from ModuleView component
- Prevent system color scheme from affecting initial page load

This ensures consistent light mode on first visit for both
public pages and admin panel, regardless of OS settings.
