Remove unused and redundant methods from canvas modules

Cleaned up the codebase by removing unused or redundant methods from Canvas, CanvasIO, CanvasLayers, CanvasLayersPanel, CanvasRenderer, and MaskTool. This reduces code complexity and improves maintainability without affecting core functionality.
