Copilot round 4:
- the EMA `interactive` arm kept `pendingStepUpRetryRef`, on a comment
claiming it was "still on its way to a redirect". That is wrong twice:
`prepareOAuthRedirect` returns before the navigation is resolved, so a
pre-navigation failure leaves the operation for a later, unrelated
step-up to re-run; and the full-page navigation destroys the closure on
the success path anyway. It now clears the ref, matching the standard
step-up below.
- the two surviving `void (async () => …)()` sites now state why the
caller cannot await, as AGENTS.md requires — the comments had described
only what the catch handles.
- the `randomUUID` fallback test restored an own descriptor that never
existed (it is inherited from `Crypto.prototype`), leaving an own
`randomUUID: undefined` that would push every later test in the file
onto the fallback path. It deletes the temporary property instead, and
asserts the global is a function again afterwards.
