Dariusz L a73a3dcf96 Add layers panel UI and improve layer management
Introduces a new CanvasLayersPanel component for managing layers visually, including selection, renaming, reordering via drag-and-drop, and deletion. Integrates the panel into the main Canvas and CanvasView, synchronizes selection and state changes, and adds logic for duplicating layers and debounced state saving. Moves IndexedDB state saving to a Web Worker for better performance. Also sets default logger level to DEBUG for improved diagnostics.
