Onboarding - add nextPath logic after email verification (#12342)

Context :
Plan choice [on pricing page on website](https://twenty.com/pricing)
should redirect you the right plan on app /plan-required page (after
sign in), thanks to query parameters and BillingCheckoutSessionState
sync.
With email verification, an other session starts at CTA click in
verification email. Initial BillingCheckoutSessionState is lost and user
can't submit to the plan he choose.

Solution : 
Pass a nextPath query parameter in email verification link

To test : 
- Modify .env to add IS_BILLING_ENABLED (+ reset db + sync billing) +
IS_EMAIL_VERIFICATION_REQUIRED
- Start test from this page
http://app.localhost:3001/welcome?billingCheckoutSession={%22plan%22:%22ENTERPRISE%22,%22interval%22:%22Year%22,%22requirePaymentMethod%22:true}
- After verification, check you arrive on /plan-required page with
Enterprise plan on a yearly interval (default is Pro/monthly).
