#### 💔 Breaking Changes

- Refactor and fix issues related to permission control APIs, with the following changes: #6804
  - Remove the `FPermission` class and all its creation methods.
  - Remove all APIs that listen for permission changes.
  - Adjust `FPermission.setPermissionDialogVisible` to `FWorkbookPermission.setPermissionDialogVisible`.
  - Remove `setPoint` and `getPoint` related methods from `FRangePermission`.
  - Add `setPoint` and `getPoint` related methods to `FRangeProtectionRule`.
  - The `setPoint` method is used to update the permission point, which will synchronize the server status in collaborative editing scenarios:
    - `false`: This permission point requires at least the `owner` role.
    - `true`: This permission point requires at least the `editor` role.
  - When creating a protected range rule, remove the `allowEdit` field from the options parameter, and use the `allowUsers` field to determine whether it is "only me" or "specified users" who can edit.
- Refactor and improve the user experience and accessibility of the collaboration status component in the upper right corner of the collaborative document, with the following changes:
  - The component no longer displays text labels, only icons, to reduce visual interference.
  - Show detailed status tips on mouse hover.
  - Add correct ARIA attributes (role, aria-live, aria-label).
  - Make the offline status clickable and support keyboard input (Enter / Space).
  - Add a spinning animation for status synchronization.
