feat: implement forgot password and reset password frontend

- Add ForgotPassword page with email submission form
- Add ResetPassword page with token validation and new password form
- Extend AuthContext with requestPasswordReset and resetPassword functions
- Add routes for /forgot-password and /reset-password in App.tsx
- Update Login page to link to forgot password flow instead of showing alert

Implements Fase 1 of frontend missing features analysis
