TestModificationViewModel is a Prism-based ViewModel that manages the test modification UI panel in the DTS Viewer application. It enables users to modify test data properties (T0 timing, sensitivity, line fit, EU multiplier/offset, filters, data flags) for selected channels, persist those modifications to files, and optionally update sensor calibration data back to the Sensor Database. The module coordinates between the UI, event-driven channel selection, and the TestModelManipulation helper class for actual data operations.
Initializes the ViewModel, sets up the View's DataContext, creates interaction requests, and subscribes to RaiseNotification, GraphSelectedChannelsNotification, ShiftT0Event, and SetUseZeroForUnfilteredEvent events.
