[FE-67] Tests for the authentication flow

[yusuftomilola]

Overview

app/(auth)/login/page.tsx, app/(auth)/register/page.tsx, store/auth.store.ts, lib/auth-api.ts, components/auth-initializer.tsx, and middleware.ts form the app's entire access boundary and have no tests.

Tasks

• Test login and register form validation using the existing React Hook Form + Zod schemas.
• Test submit states: loading disables the button, API error renders a visible message, success stores the token and redirects.
• Test the Zustand auth store: set, clear, hydrate from storage, and persistence behaviour.
• Test auth-initializer restores a session on mount and handles a missing or invalid token.
• Test route protection in middleware.ts — unauthenticated access to a dashboard route redirects to login.

Acceptance Criteria

• Both auth pages have happy-path and at least two failure-path tests.
• Auth store transitions are fully covered.
• A test proves protected routes redirect when unauthenticated.

Dependencies
