Adds the v2 onboarding **Invite team** page (`INVITE_TEAM`), shown right
after the create-profile step for the onboarding-v2 cohort. It renders
full-screen under `BlankLayout` via the shared `OnboardingV2Layout`,
matching the Figma (340px column, email inputs with inline remove, dark
Invite, Skip).

Reuses all v1 invite-team logic via a new `useInviteTeam` hook (v1
`InviteTeam` now consumes it too; its UI is unchanged). Routing mirrors
`SyncEmailsV2`/`CreateProfileV2`: new `AppPath.InviteTeamV2`, lazy
route, and an `isOnboardingV2`-gated branch in
`usePageChangeEffectNavigateLocation` (+ tests and a Storybook story).

No backend changes.
