feat: bake hackerspace-sh subsite into the management app

Ports the existing hackerspace.sh Vue site (sibling repo) into this
codebase as a route group `app/(resources)/` so a single domain serves
both the public research / games subsite and the authenticated
management app.

Routes added (all public, all prerendered):
  /resources         landing page (the original HomePage.vue)
  /zine              iframe to the printable hackerspace zine
  /governance        iframe to Governance in a Box
  /space-after-dark  iframe to the isometric exploration game
  /proposal-duel     iframe to the proposal-debate game
  /atlas             iframe to the bundled atlas.html (2.2 MB)

The individual resource paths match the originals exactly so existing
deep links and bookmarks survive the domain switch-over.

Ports six Vue components to React: Wordmark, SpaceIcon, TraceIcon,
CubeIcon, KeyIcon, GridIcon, PromptIcon, AtlasLogo, ProjectCard,
IframeWrapper. CSS scoped under `.resources-root` so the dark IBM Plex
Mono / Libre Baskerville theme cannot bleed into the management app's
shadcn design system. Fonts loaded via next/font/google. The 2.2 MB
atlas.html lives in /public.

proxy.ts adds the six routes plus /atlas.html to PUBLIC_ROUTES so
anonymous visitors can reach them without redirecting to /login.

The management landing page links to /resources twice: a "Resources"
nav link, and a callout under the CTA buttons ("Not running a space?
Read the hackerspace research and games").
