[Copilot]

Pull Request Overview

Extends the existing Random Row Selection feature from the Base Map to additional shader components (Tint Map, Parallax Map, Alpha Transition, and Emission) in the NOVA shader system, enabling consistent flipbook animation control across all shader features.

• Extended Random Row Selection functionality to Tint Map, Parallax Map, Alpha Transition Map (including second texture), and Emission Map
• Updated all shader variants (Unlit, Lit, UIParticles) with new shader properties and pragma directives
• Refactored Material Editor GUI to use shared utility methods for consistent Random Row Selection interface

• Incorrect function call - should be FlipBookBlendingProgressWithRandomRow for 3D mode (line 159 calls FlipBookBlendingProgress in the else branch)
