pypeit.dashboard.util module

Utilities for the PypeIt Dashboard GUI.

The central concern here is loud failures: by default an exception raised inside a Qt slot is swallowed by the C++ event loop, so the application silently misbehaves and the traceback is lost. These helpers ensure such failures are logged with full tracebacks (per the Debugging plan in pypeit_dashboard_coding.md).
