Walkthrough

The change updates the Stripe checkout session creation in the billing API to include the allow_promotion_codes=True parameter, enabling promotion codes during subscription purchases. It also modifies a mock authentication method to return a static empty user list for local development, and changes a frontend redirect from "/account" to "/settings" for subscribed users. No other logic or error handling is altered.

Changes

Cohort / File(s)	Change Summary
Billing API backend/aci/server/routes/billing.py	Added allow_promotion_codes=True to Stripe checkout session creation to enable promotion codes.
Mock Authentication backend/mock/propelauth_fastapi_mock.py	Modified fetch_users_in_org to return a mocked empty UsersPagedResponse instead of calling real API.
Frontend Pricing Page frontend/src/app/pricing/page.tsx	Changed redirect in PricingPage from "/account" to "/settings" when user has a non-free subscription plan.

Poem

In the warren’s code, a feature hops in,
Promotion codes now join the billing spin.
Mocked users vanish, empty and neat,
Redirects changed for a smoother seat.
With a twitch of the nose and a hop so light,
Checkout and settings now feel just right! 🐇✨

273-281: Mock implementation looks appropriate for local development.

The mock correctly returns an empty UsersPagedResponse with proper pagination metadata, preserving the expected return type and structure. The local import within the method is appropriate for a mock implementation.
