Close [BS-3268](https://linear.app/affine-design/issue/BS-3268/edgeless-下，-dark-mode-embed的配色应该更加清晰)
Close [BS-3067](https://linear.app/affine-design/issue/BS-3067/在embed上，添加split-view等相关的操作入口，基本接近page-block（见设计稿）)

## Summary by CodeRabbit

- **New Features**
  - Introduced an interactive header for embedded synced documents with fold/unfold toggle, document opening, and multiple view options.
  - Added info and copy link buttons for embedded synced documents and notes to improve document management and sharing.
- **Enhancements**
  - Updated styles for embedded synced document blocks and headers for better visual consistency.
  - Added new localization entries for header actions: "Fold", "Unfold", and "Open".

  - Unified header button components for notes and embedded synced documents into reusable components.
  - Simplified header components by delegating button behaviors to shared components.
- **Bug Fixes**
  - Fixed conditional rendering of editor content in embedded synced documents when folded.
- **Chores**
