Stage 60 — PWA API Authentication Foundation

One-stage test for memory-only PWA API authentication/session handling. No database changes and no SQL import.

1. PASS — PWA API authentication helper is present.
2. PASS — Authentication helper provides login, refresh and logout against API v1.
3. PASS — Access and refresh tokens remain memory-only and are not persisted by the PWA.
4. PASS — PWA shell loads both API client and API authentication helper.
5. FAIL — Service worker v11 caches the public API helpers and still excludes API/private application routes.
