📝 WalkthroughWalkthroughThe billing flow now distinguishes personal and team Stripe records, reports subscription status, routes existing Stripe customers to the billing portal, and supports opt-in automatic tax and tax ID collection during Checkout. Pricing and dashboard views reflect these billing states. ChangesStripe billing management
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR changes billing routing, subscription-state display, and checkout behavior, but lapsed team customers can still be sent toward a new checkout instead of billing management, and the manage-billing label can ignore the active locale. Billing records may also produce conflicting entitlement, status, and portal availability. These issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Expose the team billing portal for lapsed team customers.
Line 102 classifies a team with hasTeamStripeCustomer === true and teamSubscription === null as fully free. The page then renders FreePlanUpsell, which offers Team Checkout. TeamPlan does not render, so its /api/billing/portal?scope=team action is unavailable.
Represent lapsed team billing separately and route it to the team portal. This prevents invoice and reactivation access from being replaced with a new Checkout flow.

Load app-pricing text from the active locale.
web/app/app-pricing/page.tsx binds pricing to messages/en.json, so the canManageBilling branch always renders pricing.manageBilling in English. Use the active locale's messages and add pricing.manageBilling to all supported catalogs.

STRIPE_AUTOMATIC_TAX=1 turns on automatic_tax and tax_id_collection for both Pro and Team checkout sessions; default OFF because enabling tax against a Stripe account with no tax registration makes checkout fail. Rebuilt on main: the lapsed-portal and past_due work this branch also carried shipped separately in #11313.

Adds automatic_tax and tax_id_collection to Pro and Team Stripe Checkout sessions behind STRIPE_AUTOMATIC_TAX=1, default OFF because enabling it against a Stripe account with no tax registration makes checkout fail. Documented in web/.env.example.
Rebased and reduced: the lapsed-subscriber portal routing and past_due surfacing this PR originally carried shipped on main in #11313, so this PR is now tax-only. Per launch decision D4b the flag stays off at launch; flip it after registering tax in the Stripe dashboard.
Verification: billing-checkout-route tests pass locally including the new opt-in and default-off assertions; tsgo typecheck clean.
