`apps/backend/src/app/api/latest/internal/payments/stripe/account-info/route.ts`.

`apps/backend/prisma/seed.ts`.
> - **Schema Changes**:
> - Adds `quantity` and `offerId` columns to `Subscription` table in
`apps/backend/prisma/migrations/20250821212828_subscription_quantity/migration.sql`
and
`apps/backend/prisma/migrations/20250822203223_subscription_offer_id/migration.sql`.
> - Adds `stripeAccountId` column to `Project` table in
`apps/backend/prisma/migrations/20250825221947_stripe_account_id/migration.sql`.
> - **Improvements**:
> - Enhances purchase flow to return Stripe `client_secret` and handle
subscription upgrades/downgrades in
`apps/backend/src/app/api/latest/payments/purchases/purchase-session/route.tsx`.
> - Updates item management with new actions and protections in
`apps/backend/src/app/api/latest/payments/items/[customer_type]/[customer_id]/[item_id]/update-quantity/route.ts`.
> - Tightens validation for customer type and offer conflicts in
`apps/backend/src/app/api/latest/payments/purchases/validate-code/route.ts`.
> - **Testing**:
> - Adds extensive tests for new payment features in
`apps/e2e/tests/backend/endpoints/api/v1/internal/payments/setup.test.ts`
and
`apps/e2e/tests/backend/endpoints/api/v1/payments/purchase-session.test.ts`.
> - **Misc**:
> - Removes unused `stripeAccountId` and `stripeAccountSetupComplete`
from `branchPaymentsSchema` in
