* feat (Editor): Add an option to set the editor font family
Add the `editorFontFamily` property to the settings storage and implement font family selection functionality on editor-related pages. Also, update all pages that use the editor settings to support the newly added font family option.
* refactor(editor): Optimize the logic for editor font settings
Standardize the method for retrieving font settings on the editor page to avoid redundant calls to the `fetch()` method. Extract the font retrieval logic into variables or anonymous functions to improve code readability and performance.
