Use Login Form

1// useLoginForm — all credential-auth logic, no markup: hold the form fields, run login/register,
2// and DRIVE THE STATE MACHINE. register()/login()/verifyEmail() resolve to { state, member?,
3// stateToken? }; SUCCESS is only one of the branches. Handling every branch (email verification,
4// owner approval) and mapping MemberAuthError to a message is the bug-prone part — keep it verbatim;
5// the LoginForm component only renders what this returns. Social/SSO does NOT go through here (it's
6// a full-page redirect — see SocialButtons + the /callback page).
