refactor(editor): rewrite resize and rotate (#12054)

### 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) {}
      };
    }
  }
);
```

## Summary by CodeRabbit

- **New Features**
  - Added interaction extensions for edgeless variants of attachment, bookmark, edgeless text, embedded docs, images, notes, frames, AI chat blocks, and various embed blocks (Figma, GitHub, HTML, iframe, Loom, YouTube).
  - Introduced interaction extensions for graphical elements including connectors, groups, mind maps, shapes, and text, supporting constrained resizing and rotation disabling where applicable.
  - Implemented a unified interaction extension framework enabling configurable resize and rotate lifecycle handlers.
  - Enhanced autocomplete overlay behavior based on selection context.

- **Refactor**
  - Removed legacy resize manager and element-specific resize/rotate logic, replacing with a centralized, extensible interaction system.
  - Simplified resize handle rendering to a data-driven approach with improved cursor management.
  - Replaced complex cursor rotation calculations with fixed-angle mappings for resize handles.
  - Streamlined selection rectangle component to use interactivity services for resize and rotate handling.

- **Bug Fixes**
  - Fixed connector update triggers to reduce unnecessary updates.
  - Improved resize constraints enforcement and interaction state tracking.

- **Tests**
  - Refined end-to-end tests to use higher-level resize utilities and added finer-grained assertions on element dimensions.
  - Enhanced mouse movement granularity in drag tests for better simulation fidelity.

- **Chores**
  - Added new workspace dependencies and project references for the interaction framework modules.
  - Extended public API exports to include new interaction types and extensions.
