support ALLOWED_HOSTS env var, fix Dockerfile missing source files (#12)

- parse ALLOWED_HOSTS into vite server.allowedHosts for LAN/tailscale access
- copy src/, public/, vite.config.ts, tsconfig.json into Docker runtime stage
  (dev server needs these, only dist/ was copied before)
- pass ALLOWED_HOSTS through docker-compose

Ref #10
