/**
* Scenario:
* - Create a prepaid product where includedUsage is NOT a multiple of billingUnits
* - Attempt to attach the product
*
* Why this fails:
* - When creating Stripe tiered pricing, the first tier's `up_to` is calculated as:
* `includedUsage / billingUnits`
* - If this results in a non-integer (e.g., 50 / 100 = 0.5), Stripe rejects it
* - Stripe requires `up_to` to be a positive integer or "inf"
*
* Expected Result:
* - Error thrown during attach (when Stripe price creation fails)
