Introduces `csrfFetch` (= `makeCsrfFetch(fetch)`) in cookies.ts as a
drop-in fetch replacement that auto-injects X-XSRF-TOKEN on POST/PUT/PATCH/DELETE.

Previously 8 call sites sent mutating requests without the CSRF header —
annotation resize, comment POST/PATCH/DELETE, Geschichte CRUD, Stammbaum
relationship creation, bulk-edit PATCH, and file upload — all would fail
with CSRF_TOKEN_MISSING if the backend's cookie-based protection triggered.

All 14 client-side mutating fetches now use csrfFetch; withCsrf/makeCsrfFetch
remain in the API for injectable-fetch use cases (e.g. useTranscriptionBlocks).
