Fix: Add connect_timeout parameter to get_mcp_tools method

- Add Optional import to crew_base.py for type annotation
- Modify get_mcp_tools to accept connect_timeout parameter with 30s default
- Pass connect_timeout to MCPServerAdapter constructor
- Update existing test to verify default timeout is passed
- Add test for custom timeout values
- Add test for backward compatibility

Fixes issue #3463 where @CrewBase users couldn't configure MCP server connection timeouts
