chore: remove all Docker-related files and references

- Delete Dockerfile, docker-compose.yml, .dockerignore
- Delete docker/ directory and README
- Delete docs/install.sh (Docker-only install script)
- Delete .github/workflows/docker.yml (GHCR publish CI)
- Strip Docker mentions from .env.example, README.md,
  docs/index.html, client/vite.config.ts, server/src/index.ts

(Plain `npm run dev -- --host` does *not* work here: the root `dev` script is a `concurrently` wrapper, so the flag never reaches Vite.) API calls go through Vite's dev proxy, so no extra server config is needed.
