Add dashboard example showing realistic admin panel

This example demonstrates all key Iris features for internal tool teams: - Multiple pages with client-side routing - Auth-protected sections with route guards - Reactive data display with signals - Form inputs (text, checkbox, slider, select) - Component composition with reusable layouts Test credentials: admin/admin (full access) or user/user (limited access) Closes #8 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
