Refactors all custom CSS class names to include an 'lf-' prefix
(e.g. .painter-button -> .lf-painter-button, .clipboard-switch -> .lf-clipboard-switch).
This isolates LayerForge styles within the ComfyUI DOM and prevents
CSS namespace collisions with other custom nodes or host page styles.
Changes span src/ TypeScript source files and src/css/ stylesheets.
Fixed LayerForge fullscreen mode displaying behind ComfyUI interface elements by increasing z-index from 111 to 999999. Fullscreen mode now properly overlays all UI components as intended.
Moved inline CSS from CanvasView.js to a dedicated canvas_view.css file and added dynamic stylesheet loading. Extracted tooltip and shortcut HTML into separate template files and implemented a ResourceManager utility for loading stylesheets and templates. Updated CanvasInteractions.js and CanvasView.js to use the new resource management and template loading approach, improving maintainability and modularity.
