Feature 4: Webinterface — React-Frontend, Discord-OAuth2, REST-API

- Discord-OAuth2-Login (identify-Scope, CSRF-State, signierte Session-Cookies, keine Token-Speicherung)
- REST-API: /api/devlogs (öffentlich), /api/commits (nur ADMIN_DISCORD_ID), /api/me
- React + Vite Frontend: Devlog-Archiv mit Mini-Markdown-Renderer, Commit-Tabelle, dunkles EcoGame-Theme
- Fastify liefert frontend/dist mit SPA-Fallback aus; Vite-Dev-Proxy für lokale Entwicklung
- Multi-Stage-Dockerfile (Frontend-Build im Image), neue Env-Vars in Compose + .env.example
- README: OAuth2-Setup (Redirect-URLs, Client Secret) und Frontend-Workflow
