fix(plugin-ecommerce): pass req to Payload API calls in Stripe adapter (#15839)

### What?

Adds the missing `req` parameter to all `payload.find()`,
`payload.create()`, and `payload.update()` calls in the Stripe adapter's
`confirmOrder.ts` and `initiatePayment.ts`.

### Why?

Without `req`, hooks on transactions/orders/carts receive an empty
request context, and each database call runs in an isolated session —
breaking transactional consistency (e.g. order created but cart not
marked as purchased on failure).

### How?

Pass the existing `req` (already available in scope) to each Payload API
call. Also fixes `payload.logger.error` calls to use the correct object
form per project conventions.

Fixes #15836
