Start a sign-in email change

Sends a confirmation link to the new email address. Only the Person themself may call this operation with a signed-in session; API keys are not accepted. Requires recent MFA step-up for HighRiskWriteAction. Confirming the change signs the Person out of every V3 session. The new address then becomes both the sign-in and displayed email address.

Requires a session with recent MFA step-up for HighRiskWriteAction. If step-up is missing or expired, this operation returns 403 StepUpMfaRequired; create and verify an MFA challenge at /v3/platform/mfa-challenges with requiredFor: "HighRiskWriteAction", then retry.

Optional idempotency token for authenticated POST and PATCH requests. Reusing the same key and body returns the cached response for 24 hours, except credential operations that explicitly document a 409 because one-time secret material is never cached; reusing it with a different body returns 409 IdempotencyKeyConflict. Use 1-255 printable ASCII characters.
