Road to No Explicit Any Part 5: load3d Module (#8064)

## Summary
- Removes all `any` types from the load3d module
- Uses generics for EventCallback to provide type-safe event handling
- Types node parameters with LGraphNode
- Types onExecuted callback with NodeExecutionOutput
- Types Camera Config property casts with CameraConfig interface

## Changes
- `interfaces.ts`: EventCallback<T> generic, EventManagerInterface
generic methods
- `EventManager.ts`: Generic
emitEvent/addEventListener/removeEventListener
- `AnimationManager.ts`: setupModelAnimations originalModel typed as
GLTF union
- `Load3d.ts`: Event listener methods use EventCallback<T>
- `load3d.ts`: Node params typed as LGraphNode, onExecuted uses
NodeExecutionOutput, CameraConfig casts

## Test plan
- [x] `pnpm typecheck` passes
- [x] `pnpm lint` passes
- [x] `pnpm test:unit` passes
