refactor(docker): simplify Dockerfile and remove custom browser component

- Simplified Dockerfile by removing system dependencies, Playwright installation, and unnecessary Python packages
- Removed custom browser_use_component.py (now using custom_components directory)
- Updated docker-compose to build from Dockerfile and mount custom_components
- Retained only essential dependencies: browser-use and langchain-openai
