UiImage -> ImageNode, UiImageSize -> ImageNodeSize (#16271)
# Objective

Align `UiImage` with the new `XNode` naming convention.

## Solution

- Rename `UiImage` to `ImageNode`
- Rename `UiImageSize` to `ImageNodeSize`

---

## Migration Guide

Before:
```rust
commands.spawn(UiImage::new(image));
````

After:
```rust
commands.spawn(ImageNode::new(image));
```
