Fix MCP tool exposure to show only search_web

- Add api_name=False to button click and demo.load to hide from API
- Use gr.api() to explicitly expose only search_web as MCP tool
- Move docstring to proper position after function signature
- Maintains GUI functionality while providing clean MCP interface
