Use setup.py post-install hook for Playwright Chromium installation

- Remove runtime subprocess install (FastMCP Cloud doesn't allow disk writes)
- Add setup.py with cmdclass hooks to install Chromium at build time
- Rename requirements.txt so FastMCP Cloud uses pyproject.toml instead

mcp_server_main.py
