"""Task 1 (sub-step 6b) — EventTable / EventDetailPanel widget smoke tests.

These instantiate real PySide6 widgets against the offscreen QPA platform
(no display needed, no pytest-qt dependency — a plain QApplication instance
is enough to construct/query widgets, only an actual event loop would need
more). Verifies the extraction into presentation/monitoring/shared/ wires up
without error and preserves the pre-refactor row/column behaviour.
