style: apply Black auto-formatting

Black reformatted code according to MONAI's style requirements:
- Add blank line after module docstring
- Remove extra blank lines before class definition
- Reformat long assertions to Black's multi-line style

Note: Some lines exceed 120 chars due to f-string messages, which are
allowed per setup.cfg (E501 ignored for strings).
