Configures both previously-empty test runners (vitest.config.ts,
playwright.config.ts) and adds the typed lib/api client layer (axios +
interceptors), the session-cookie plumbing (lib/auth), TanStack Query
infrastructure (lib/query, providers), and a real sign-in flow consuming
supporthub-api's own login (010-identity-auth) - the true foundation
every other user story in this feature depends on.
Two structural fixes to the existing scaffold, both found only by
running the app rather than by inspection: middleware.ts belongs at
src/middleware.ts under this project's src/ layout, not the repo root;
and next.config.mjs's output:'export' is incompatible with Next.js
Middleware outright (the dev server refuses to start it), so this app
now runs as a standard Next.js server - confirmed with the user before
making that deployment-mode change.
Verified end-to-end with a real, locally-running supporthub-api: all 5
Playwright scenarios (unauthenticated redirect, sign-in, wrong-password
generic error, non-admin role gating, sign-out) pass against a live
backend, not a mock.
