• Correlation report plots no longer include history vectors. If a history vector such as WOPRH is requested, the report is created for the simulated vector (WOPR) instead.
• The RFT correlation report uses the depth type and unit from the source plot.
• The Curve Appearance panel, toolbar button and global appearance settings are hidden behind the curve-appearance experimental feature. The keyword is a shared constant, RiaExperimentalFeatures::curveAppearanceKeyword.

Looks fine:

• Null checks for m_curveStyleRulesView are in place at all three places that use it.
• nativeVectorNames({x}).front() is safe because one input always gives exactly one output.
• The RFT depth type is limited to MD/TVD, which matches calculateValueOptions. setDepthUnit runs after applyDepthTypeToSubPlots, and the depth-range conversion uses m_wellRftPlot->depthUnit(), so the unit carries over correctly.
