fix(ui): make loras widget fixed-size with user-controlled node resize

Remove dynamic height calculation that auto-resized the node when
LoRAs are added or removed. The widget now stays at the size the user
sets via the node resize handle, scrolling when content overflows.

- Drop updateWidgetHeight() and hardcoded entry-count height math
- Set --comfy-widget-min-height once (200px) instead of recalculating
- In Vue mode: add contain:layout+size to break the ResizeObserver
  feedback loop that forced node growth with content (CSS via
  .lm-loras-container.lm-vue-node scoped to vueNodesMode only)
- Remove unused "Node 2.0: Maximum visible LoRA entries" setting
