Rebuild openclaw from npm instead of premade image, configure Ollama

- Add Dockerfile using node:22-bookworm-slim + npm install -g openclaw@latest
- Update docker-compose.yml: use local build, add OLLAMA_API_KEY=ollama-local,
  remove legacy OPENCLAW_AGENT_PROVIDER/MODEL/OLLAMA_BASE_URL env vars
- Add setup.sh to create openclaw.json with explicit Ollama provider config

Key fixes vs previous attempt:
- Config file is openclaw.json (not config.json or auth-profiles.json)
- models.providers.ollama needs baseUrl with /v1 suffix + explicit model list
- OLLAMA_API_KEY env var is required to opt in to Ollama support
- reasoning:false on models prevents 400 errors from Ollama
