feat: add PasswordAuth blueprint illustration

The primary-auth feature RememberMe composes onto. Transcribed from the
ontology password-auth README + .als: the full AuthState lifecycle
(Idle / Submitting / Authenticated / Refreshing / LockedOut / Error), its
8 functions, and a sign-in specimen shown across those states. Adds the
auth transition kinds and wraps the state-machine legend to a second row
so this richer machine's kinds fit without clipping.
