feat(auth): unify and polish login, register and homepage auth UI

Login and register each carried their own copy of the promo panel and the error banner, so the two pages drifted apart and every caller had to wire role="alert" by hand. Extract a shared AuthPromoCard and AuthAlert, use them in both forms and for the login notices, and link errors to their fields via aria-invalid / aria-describedby. Focus now lands on the 2FA code field the moment it appears, the credential fields lock while a request is in flight, and invalid inputs get a danger tint. The homepage top bar was a byte-for-byte duplicate of AuthTopBar; it now renders the shared component, and the compact homepage login uses the tighter spacing its comment already promised.
