🐛 Issues Fixed

Issue 1: SSR Error

Problem: useTheme must be used within a ThemeProvider error during build

Solution: Changed ThemeContext to have a default value instead of undefined:

const ThemeContext = createContext<ThemeContextType>({
  theme: "dark",
  toggleTheme: () => {},
  setTheme: () => {},
});

Issue 2: Import Path

Problem: useOrderContract hook not found

Solution: Copied hook file to frontend/hooks/ directory
