Changes the authenticated member's password. The caller supplies their
current password and a new password; the current password is verified before
any change is made. Only email_and_password accounts may use this endpoint —
OTP and social/SSO (Google, Apple) accounts are rejected. The new password
must satisfy the same rules as the password-reset flow.
Password changed successfully.
