iOS Safari in PWA standalone mode unreliably handles cookies, causing
CSRF token desync between client and server after app resume. Previous
fixes (response body token in /auth/me and /auth/login) still left a
window where the token could go stale.
Now the server sends X-CSRF-Token response header on every API response
(via csrfMiddleware), including 403 error responses. The client reads
this header from every response, enabling instant self-healing: a 403
extracts the correct token from the error response itself and retries
without needing an extra /auth/me round-trip.
SW cache bumped to v33 to ensure existing iOS PWA installs pick up the
new client code.
iOS Safari (especially PWA/standalone mode) unreliably exposes cookies
via document.cookie, causing CSRF token mismatch on state-changing
requests. The CSRF token is now included in /auth/login and /auth/me
response bodies and stored in-memory on the client. Cookie remains as
fallback. Retry mechanism also improved to read token from response
body and handle expired sessions.
Dashboard-Widgets aktualisierten nicht, weil der Service Worker die
alte router.js aus dem Cache servierte (stale-while-revalidate).
Cache-Version v15→v16 erzwingt Invalidierung aller gecachten Dateien.
Zusätzlich fetch cache:no-store auf allen API-Aufrufen als Absicherung.
