[FE-141] register/login pages have no visible client-side handling for the backend's auth-specific throttle

[mftee]

Overview

app/(auth)/login/page.tsx and register/page.tsx — the backend applies @Throttle({ auth: { limit: 10, ttl: 60_000 } }) on AuthController. No test coverage confirms the frontend shows a clear, specific message (e.g. "too many attempts, try again in N seconds") when it receives a 429, as opposed to a generic error.

Tasks

• Add explicit handling for a 429 response on login/register with a clear, specific message.
• Add a test for this case.

Acceptance Criteria

• A rate-limited login/register attempt shows a specific, accurate message rather than a generic error.
