Fix all mypy type checking issues

- Added boto3-stubs for proper type checking
- Fixed missing type annotations in function parameters (**kwargs -> **kwargs: Any)
- Fixed FileTransferSession to use _logger and _config from parent Session class
- Added proper return type annotations for iterator and async functions
- Fixed termios tcsetattr type compatibility with Any type annotation
- Added type ignore comments for boto3.Session constructor issues
- Fixed signal handler parameter names with underscores to indicate unused
- All 34 source files now pass mypy type checking successfully
