The breadcrumb's trailing span pulls its label from pageBreadcrumbTitle,
which pages set in script setup after a useFetch. SSR rendered the URL
slug there; client rendered the title; Vue logged a hydration text
mismatch on every detail page.
Wrap the last segment's span in ClientOnly with an nbsp fallback so the
SSR DOM stays the same shape but defers the text to the client. The
prior attempt at this in layouts/default.vue + layouts/admin.vue was
reverted on this branch — it changed segment counts and produced a
worse node-structure mismatch.
Migrate the entire admin section from the dark guild-* Tailwind theme
to the zine design system (dashed borders, CSS custom properties,
Brygada 1918 + Commit Mono, cream/dark mode palette).
- Replace admin top-nav layout with sidebar matching default layout

- Reskin events/create and series/create form pages
- Add dev-only test login endpoint (GET /api/dev/test-login)
