feat: LiveServer-M1 v1 — educational video conferencing platform

Full MVP implementation:
- Next.js 16 + React 19 + TypeScript + Tailwind CSS v4
- LiveKit integration (rooms, tokens, webhooks, moderation)
- better-auth (email/password, sessions, roles)
- Prisma 7 + PostgreSQL (9 models, 3 enums)
- 15 API routes (auth, rooms, lobby, chat, files, moderation, hand-raise)
- 7 pages (landing, auth, dashboard, join, video room)
- SSE-based waiting room with host approval flow
- Security: PIN rate limiting, session fingerprint bans, chat/files auth
- Python AI Agent (Deepgram STT + OpenAI summarization)
- Docker Compose (local + production with Traefik + Let's Encrypt)
- Interactive setup script (setup.sh)
- Dev protection middleware (DEV_ACCESS_KEY, ALLOWED_IPS)
