Detailed Description

cvRenderViewSelectionReaction handles all selection modes in a single class

This class follows ParaView's pqRenderViewSelectionReaction pattern:

One instance per selection action (button/menu item)
Static ActiveReaction tracks the currently active selection
beginSelection()/endSelection() handle all state transitions
All cursor, interactor style, and observer management is internal

Key improvements over the previous multi-layer architecture:

No separate cvViewSelectionManager layer
No separate cvRenderViewSelectionTool layer
All selection logic in one place for easier maintenance
Direct alignment with ParaView's proven architecture
