Fixes #15063

When a grid statistics histogram is filtered by 3D view visibility, zoom all in the plot when the filter view is changed or when the cell visibility in the 3D view is updated.

• RimHistogramDataSource gets a new zoomAllRequested signal
• RimGridStatisticsHistogramDataSource sends it after updating data for filter changes, and no longer depends on RimHistogramPlot
• RimHistogramCurve handles the signal and calls zoomAll() on its plot

Copy/paste of a histogram curve:

• initAfterRead() is re-run after references of a pasted curve are resolved, so the 3D view visibility filter is restored
• The axis scale of the destination plot is set from the binning mode of the pasted curve (RimHistogramCurve::updateAxisScaleFromBinningMode())

No critical or high-severity issues. These were checked and look fine:

• Removing the RimHistogramPlot.h include is safe: RimHistogramDataSource.h already includes it.
• initAfterInsert() re-runs initAfterRead() on the curve subtree. All of those (curve, grid statistics data source, RimEclipseResultDefinition, RimPlotCurveAppearance) are idempotent, and re-connecting signals does nothing.
• Signal order is correct: dataSourceChanged is sent before zoomAllRequested.

Findings: 2 medium, 3 low (see inline comments). Low: there are no tests for the paste path. A small test that copies a curve and checks that m_property has an eclipse case set after initAfterInsert() would guard against regressions.
