Align with Polar model: one product = one price. METERED prices are filtered at API level, so SDK consumers only see the base price. - ProductSchema.price is now singular (nullable) - CheckoutProductSchema.price is now singular (nullable) - Added currency field to price objects
Create shared CurrencySchema (z.enum(["USD", "SAT"])) in schemas/currency.ts and use it throughout the API contract for type safety and validation. - Add src/schemas/currency.ts with CurrencySchema and Currency type - Update checkout.ts, products.ts, invoice.ts to use CurrencySchema - Export CurrencySchema from index.ts
