feat: add employee email verification on signup

- Signup sends verification email instead of auto-login; login blocks unverified emails
- New endpoints: POST /verify-email and POST /resend-verification
- New verify-email page in dashboard with token-based email confirmation
- DB migration adds emailVerified and emailVerificationToken fields to Employee
- Update sign-in/sign-up/reset-password flows to handle verification states
- Minor UI polish across dashboard and marketplace components
- Refactor marketplace-homepage types
