generateIdempotencyKey falls back to Math.random on non-secure origins #706
Description
Problem
When crypto.randomUUID is missing, which happens on any non-secure context such as a plain-http staging deploy (not just "very unlikely browsers"), keys are built from Math.random(). Those are predictable and collision-prone, and since keys are scoped per caller on the backend, a collision replays someone's cached response instead of executing.
Suggested fix
Fall back to crypto.getRandomValues (available on insecure origins) to build a v4 UUID.
