Fixes [BS-3528](https://linear.app/affine-design/issue/BS-3528)
Fixes [BS-3331](https://linear.app/affine-design/issue/BS-3331/frame-移动逻辑很奇怪)
### Changed
- Remove `onSelected` method from gfx view, use `handleSelection` provided by `GfxViewInteraction` instead.
- Add `selectable` to allow model to filter out itself from selection.
- Frame can be selected by body only if it's locked or its background is not transparent.

Close [BS-3507](https://linear.app/affine-design/issue/BS-3507/edgeless-text-颜色无法-undoredo)
Close [BS-3426](https://linear.app/affine-design/issue/BS-3426/frame-修改背景色后不能撤销)
This PR fixes the issue where the color change of edgeless blocks could not be undone/redone, including notes, edgeless-text, and frames. It also addresses the problem of a tiny shape being unexpectedly retained on the canvas. The key changes are:
- Removal of `transact` from the `pop` method of edgeless elements.
- Refactoring of `onPickColor` for all edgeless elements and blocks to better control the lifecycle of custom color property changes.
- Addition of the missing custom background color feature for notes.
- Addition of undo/redo color tests for notes, frames, and edgeless-text.

### Changed
This pr split the old `edgeless-selected-rect` into four focused modules:
- `edgeless-selected-rect`: Provide an entry point for user operation on view layer only, no further logic here.
- `GfxViewInteractionExtension`: Allow you to plug in custom resize/rotate behaviors for block or canvas element. If you don’t register an extension, it falls back to the default behaviours.
- `InteractivityManager`: Provide the API that accepts resize/rotate requests, invokes any custom behaviors you’ve registered, tracks the lifecycle and intermediate state, then hands off to the math engine.
- `ResizeController`: A pure math engine that listens for pointer moves and pointer ups and calculates new sizes, positions, and angles. It doesn’t call any business APIs.
### Customizing an element’s resize/rotate behavior
Call `GfxViewInteractionExtension` with the element’s flavour or type plus a config object. In the config you can define:
- `resizeConstraint` (min/max width & height, lock ratio)
- `handleResize(context)` method that returns an object containing `beforeResize`、`onResizeStart`、`onResizeMove`、`onResizeEnd`
- `handleRotate(context)` method that returns an object containing `beforeRotate`、`onRotateStart`、`onRotateMove`、`onRotateEnd`
```typescript
import { GfxViewInteractionExtension } from '@blocksuite/std/gfx';
GfxViewInteractionExtension(
flavourOrElementType,
{
resizeConstraint: {
minWidth,
maxWidth,
lockRatio,
minHeight,
maxHeight
},
handleResize(context) {
return {
beforeResize(context) {},
onResizeStart(context) {},
onResizeMove(context) {},
onResizeEnd(context) {}
};
},
handleRotate(context) {
return {
beforeRotate(context) {},
onRotateStart(context) {},
onRotateMove(context) {},
onRotateEnd(context) {}
};
}
}
);
```

### TL;DR
For canvas elements, this PR adds placeholders during zooming operations to improve performance.

### What changed?
- Implemented placeholder rendering during zooming operations in the canvas renderer, but not only DOM.
- Added a `forceFullRender` property to the `GfxCompatibleInterface` to allow elements to opt out of placeholder rendering
- Set `forceFullRender = true` for connectors to ensure they always render properly, even during zooming
- Connected the turbo renderer to the viewport's zooming state to automatically switch between full and placeholder rendering
### Why make this change?
Rendering complex elements during zooming operations can cause performance issues and make the UI feel sluggish. Rendering connector label also leads to high cost DOM `set font` delays.

The turbo renderer improves performance by displaying simple placeholders for elements during zooming, while still rendering critical elements like connectors fully. This creates a smoother user experience while maintaining essential visual information.
