test(nodeModeChange): fix tests after mode change refactoring

After refactoring mode change logic from lora_stacker.js to main.ts
(compiled to lora-manager-widgets.js), updateConnectedTriggerWords became
a bundled inline function, making the mock from utils.js ineffective.

Changes:
- Import Vue widgets module in test to register mode change handlers
- Call both extensions' beforeRegisterNodeDef when setting up nodes
- Fix test node structure with proper widget setup (input widget with
  options property and loras widget with test data)
- Update test assertions to verify mode setter configuration via property
  descriptor check instead of mocking bundled functions

Also fix Lora Cycler widget min height from 316 to 314 pixels.
