v2 onboarding: dedicated verify step and upgrade-free-trial as the last step (#22303)

https://github.com/user-attachments/assets/b1ee4f77-c6d7-4638-b9f1-dd801d1cc0db

Completes the onboarding-v2 flow: a dedicated verify step, the
reordering that makes the plan step come last, and the
upgrade-free-trial page itself.

## Verify step (`/verify-v2`)
After the cross-domain token exchange, v2 sign-ups land on a clean
`BlankLayout` "Verifying your email" screen (fading Twenty logo) instead
of the v1 `AuthModal` flashing over the background mock. The redirect
target is chosen from `isOnboardingV2` (read from the Jotai store at
redirect time). The pulsing logo is extracted into a shared
`OnboardingPulsingLogo`, reused by the workspace-activation loader.
`/verify-v2` joins the same exempt lists as `/verify` (ongoing-creation
guard, metadata gater, apollo unauthenticated handler, captcha, page
title) — intentionally not `useShowAuthModal`, which is what drops the
modal.

## Plan step is now last
`getOnboardingStatus` checks `PLAN_REQUIRED` after invite-team instead
of first, so onboarding runs workspace activation → email → profile →
invite → plan. This is what lets the upgrade step be reached as the
final step instead of gating right after sign-up. Applies to both v1 and
v2 (same order).

## Upgrade free trial page (`PlanRequiredV2` → `ChooseYourPlanV2` /
`UpgradeFreeTrial`)
The final step, full-screen under `BlankLayout` via
`OnboardingV2Layout`, matching the Figma (billing card with the Stripe
form, the "Basic / without credit card" option, trial + credits pills).
Reuses the v1 `ChooseYourPlanContent` billing logic
(`SubscriptionPaymentForm`, `useHandleCheckoutSession`). The "+N free
credits" reward comes from
`clientConfig.onboarding.upgradeCreditsReward` (sourced from
`BILLING_FREE_WORKFLOW_CREDITS_FOR_TRIAL_PERIOD_WITH_CREDIT_CARD`).

## Also
Fixes a latent staleness in the Apollo `onUnauthenticatedError` handler
— it captured `location` from the memoized client, now read via a ref —
so auth-path exemptions are correct after navigation.

Note: the onboarding step order change affects v1 too (plan becomes its
last step as well).
