Replaces mock integration data in Settings.tsx with live calls to
api.listIntegrations/createIntegration/updateIntegration/testIntegration.
Also fixes apiFetch sending Content-Type: application/json on bodyless
requests, which made Fastify reject Test Connection calls with 400.

- New AuthContext drives app state (loading/needs-setup/enrolling/
logged-out/logged-in) by checking GET /api/system/setup-status and
GET /api/auth/me on load; JWT stored in localStorage
- Enrollment page: step 1 creates the admin account via POST /api/setup,
step 2 lets you connect integrations (or skip) before entering the app
- Login page for returning sessions; TopBar's Sign Out now calls
logout() instead of being a dead link
- Verified end-to-end in a browser: fresh setup -> connect/skip ->
dashboard, reload persists the session, sign out -> login -> back in
