The test_query_one_optional test did not verify that WrongType exceptions propagate correctly when a widget is found but has an incorrect type, despite this behavior being documented in the method's docstring.

Changes

• Added test case verifying WrongType is raised when query_one_optional("#foo", Label) is called on an Input widget
• Mirrors the pattern used in test_query_error for consistency

# Verify that WrongType exceptions still propagate
with pytest.raises(WrongType):
    # Asking for a Label, but the widget is an Input
    app.query_one_optional("#foo", Label)

This ensures query_one_optional maintains its documented contract: catch NoMatches (return None), but propagate WrongType.
