Dockerfile.prod päivitetty Astro-frontendille

Muutokset:
- Vaihe 1: Node.js buildaa Astro-frontendin (frontend/dist/)
- Vaihe 2: wasm-pack buildaa Wasm-moduulin erikseen
- Vaihe 3: Hub rakennetaan Rustilla
- Vaihe 4: Yhdistetään dist/ + pkg/ + avatars/ + templates/ + GUIDE.md

STATIC_DIR=/app/frontend/dist (ei enää /app/static)
Avatarit, templates ja GUIDE.md kopioidaan erikseen koska
Astro ei kopioi public/-tiedostoja dist/:iin buildin yhteydessä.
