## Summary
- Enables `MustVerifyEmail` on the `User` model so new users must verify
their email before accessing protected routes
- Unverified users are redirected to `/email/verify` when attempting to
access routes behind the `verified` middleware (subscribe, onboarding,
dashboard)
- A verification email is automatically sent on registration via Fortify

## Test plan
- [x] New test: registration sends a `VerifyEmail` notification
- [x] New test: newly registered users have `email_verified_at` as null
- [x] New test: unverified users are redirected to `verification.notice`
from protected routes (subscribe, onboarding, dashboard)
- [x] New test: verified users are not redirected to verification notice
- [x] Existing email verification and notification tests still pass (31
auth tests, 52 settings tests)
- [x] Browser walkthrough: registration → redirected to `/email/verify`
page with "Resend verification email" button
