Subject: [PATCH] feat: implement light mode with theme toggle

Closes #1

- Added Tailwind dark mode class strategy
- Created ThemeContext with localStorage persistence
- Added ThemeToggle button component (sun/moon icons)
- Updated all components with light mode colors:
  - Layout: bg-gray-50 in light, bg-zinc-900 in dark
  - Header: bg-white in light, bg-zinc-800 in dark
  - Modal: bg-white in light, bg-zinc-800 in dark
  - Form inputs: proper contrast in both modes
  - Buttons: appropriate hover states for both modes
- RainbowKit theme switches between lightTheme and darkTheme
- Respects system preference (prefers-color-scheme)
- Persists user choice in localStorage
