Why
Stripe and Tempo idempotency keys currently use Java-specific prefixes. The wire-visible namespace should identify MPP rather than a particular SDK.
What
Changed Stripe PaymentIntent and Tempo relay idempotency key prefixes to
mpp_while preserving their existing suffix construction. Updated the affected regression tests.Retries that begin before the upgrade and continue after it will use a different key at the version boundary.
