fix(lit-components): fix rendering and interaction issues in force-graph, html-table, and draggable-dom

- lit-force-graph: Refactored for instance reuse, better lifecycle management, and added dynamic imports for AR/VR modes.
- lit-html-table: Improved visual design, readability of headers, and fixed reactivity in editable mode.
- lit-draggable-dom: Fixed clipping issues by switching to relative/absolute positioning and resolved a panning speed bug caused by CSS variable inheritance.
