## Summary by CodeRabbit

* **New Features**
* Added support for comments on graphical elements, allowing users to
comment on both blocks and graphical elements within surfaces.
* Enhanced comment previews to include graphical elements in selection
summaries.
* Improved editor navigation to focus on commented graphical elements in
addition to blocks and inline texts.

* **Bug Fixes**
* Updated comment highlighting and management to consistently use the
new comment manager across all block and element types.

* **Refactor**
* Renamed and extended the comment manager to handle both block and
element comments.
* Streamlined toolbar configurations by removing outdated comment button
entries and adding a consolidated comment button in the root toolbar.

* **Tests**
* Disabled the mock comment provider integration in the test editor
environment to refine testing setup.
