pyproject(mypy): add sphinx_fonts to ignore_missing_imports

why: sphinx_fonts is a local docs/_ext extension, not an installed
package — mypy cannot resolve it at analysis time.
what:
- Add sphinx_fonts to [[tool.mypy.overrides]] ignore_missing_imports
- Add mypy ignore-errors directive to test_sphinx_fonts.py
