Valida a assinatura do authenticator e emite JWT + cookies (login normal).

Motivo: fecha o ceremony e faz login efetivo. Piso §3 — auth server-side; JWT emitido apenas após a library confirmar a assinatura contra a public key persistida. Comportamento: (1) decoda body {challenge_id, credential}; (2) loadChallenge (SessionData + user_id que foi salvo no begin); (3) reconstrói user com credentials atuais; (4) ValidateLogin da library; (5) UPDATE sign_count + last_used_at do credential; (6) writeFreshSession (JWT + cookies).

Entradas: body {challenge_id, credential (JSON do authenticator)}.

Retorno: 200 {id, email, name}; 401 challenge/credential inválido; 500 falha DB; 503 se webauthn desativado. Efeito: 1 SELECT + 1 DELETE (challenge) + 1 SELECT (creds) + 1 UPDATE (sign_count) + 1 INSERT (auth_refresh_tokens) + cookies.
