feat: command palette (Ctrl+K), dark mode, pinned clients

- Global Command Palette: Ctrl+K search across clients, pages, and actions
  - Arrow key navigation, grouped results (Pages/Clients/Actions)
  - Keyboard hints in footer
- Dark mode: full theme toggle (light/dark/system) with localStorage
  - Theme toggle in header bar
  - Dark mode applied to Layout, Dashboard, Clients, ClientDetail, Login, Modal
  - Tailwind v4 @custom-variant for class-based dark mode
- Pinned/Favorite clients: star clients for quick dashboard access
  - Pin button on client detail page and dashboard recent clients
  - Pinned clients grid on dashboard
  - Uses localStorage (no backend changes needed)
- Search bar trigger in header with ⌘K shortcut hint
