Changes the signed-in buyer's password (currentPassword, password). A wrong current password is 400 with fieldErrors.currentPassword. Every session of the buyer is signed out: sign in again at POST https://apis.kentro.live/auth/login/customer. Password reset for a buyer who forgot it is on apis.kentro.live/auth/password-reset/customer/*.
Who may call it: A signed-in buyer (X-Storefront-Buyer); without one the answer is 401 UNAUTHORIZED.
