[refactor] remove node as dependency in 3d node (#6707)

## Summary

This PR refactors the Load3d 3D rendering system to remove its direct
dependency on LGraphNode, making it a more decoupled and reusable
component. The core rendering engine is now framework-agnostic and can
be used in any context, not just within LiteGraph nodes.

## Changes

1. Decoupled Load3d from LGraphNode
  - Before: Load3d directly accessed node.widgets and node.properties
- After: Load3d accepts optional parameters and callbacks, delegating
node integration to the calling code

2. Event-Driven State Management
  - Removed internal storage from Load3d core components
- Camera, controls, and view helper managers now emit cameraChanged
events instead of directly storing state
- External code (e.g., useLoad3d) listens to events and handles
persistence to node.properties

3. Reactive Dimension Updates

- Introduced getDimensions callback to support reactive dimension
updates
- Fixes the issue where dimension changes in vueNodes mode required a
refresh
- The callback is invoked on every render to get fresh width/height
values

4. Improved Configuration System

- Load3DConfiguration now accepts properties: Dictionary<NodeProperty |
undefined> instead of custom storage
  interface
  - Uses official LiteGraph type definitions (Dictionary, NodeProperty)
  - More semantic parameter naming: storage → properties
