Introduces helper methods to reduce code duplication and improve readability in CanvasInteractions. Mouse coordinate extraction, event prevention, zoom operations, drag-and-drop styling, and layer wheel transformations are now handled by dedicated methods. This refactor centralizes logic, making the codebase easier to maintain and extend.
