fix: improve loras widget drag functionality in Vue DOM render mode

- Use pointer events (pointerdown/pointermove/pointerup/pointercancel) with proper capture
- Fix drag not updating strength values by avoiding re-renders during drag
- Fix cursor stuck in resize state by ensuring proper cleanup
- Fix cursor showing wrong icon on hover (should be pointer)
- Ensure strength values display fixed width with 2 decimal places
- Remove unnecessary data-capture-wheel attribute (no wheel adjustment in loras widget)
- Add font-variant-numeric: tabular-nums for consistent number display

This ensures loras widget works consistently in both Canvas and Vue DOM render modes.
