fix: Clean up runtime dependencies

Removed (unused):
- setuptools: Uses importlib.metadata.entry_points (stdlib)
- urllib3: Only urllib.parse (stdlib) is used
- faker: No imports found anywhere in codebase

Moved to optional [viz] extra:
- matplotlib: Only for Diagram.draw()
- ipython: Only for Diagram.make_svg() in Jupyter

Install with visualization: pip install datajoint[viz]
