feat: better repr for WeakCallback objects

[tlambert03]

for easier debugging

Summary by CodeRabbit

• Refactor: Updated import statements and class names in src/psygnal/_signal.py and src/psygnal/_weak_callback.py for improved consistency and clarity.
• New Feature: Added object_repr() method to the WeakCallback class in src/psygnal/_weak_callback.py to provide a human-readable representation of an object.
• Test: Introduced a new print statement in tests/test_weak_callable.py for better debugging during testing.
• Chore: Added a conditional step in the CI/CD pipeline .github/workflows/test.yml to run tests using a headless GUI, improving test coverage.
