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).

Enlarge the centre-on-person, panel-close, and affordance-dismiss icon buttons
to 44x44 hit areas (WCAG 2.5.8, UX review) while keeping the small glyphs.

Add an onCentre control to StammbaumSidePanel (title row, both desktop aside
and mobile sheet). The page drives a one-shot centreOnId so StammbaumTree
recentres the canvas on the focal node (US-PAN-005). Also tighten the panel
spec's deathYear fixture to a valid type.
