fix: rewrite selection logic and frame selection handling logic (#12421)

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.

## Summary by CodeRabbit

- **New Features**
  - Enhanced selection behavior for frames, edgeless text, notes, and mind map elements with refined control based on lock state and background transparency.
  - Introduced group-aware selection logic promoting selection of appropriate group ancestors.
  - Added support for element selection events in interactivity extensions.

- **Bug Fixes**
  - Resolved frame selection issues by enabling selection via title clicks and restricting body selection to locked frames or those with non-transparent backgrounds.

- **Documentation**
  - Added clarifying comments for group retrieval methods.

- **Tests**
  - Updated and added end-to-end tests for frame and lock selection reflecting new selection conditions.

- **Refactor**
  - Unified and simplified selection handling by moving logic from component methods to interaction handlers and removing deprecated selection methods.
  - Streamlined selection candidate processing with extension-driven target suggestion.
  - Removed legacy group element retrieval and selection helper methods to simplify interaction logic.

- **Style**
  - Renamed types and improved type signatures for selection context and interaction configurations.
