Introduce the EasyMDE markdown editor into the admin interface, providing enhanced
markdown editing capabilities. This integration caters to users preferring a dedicated
markdown editor with additional features and a streamlined user experience.
Due to the recommendation for better performance and user experience,
the default editor in both configuration files and view templates has been
switched from ueditor to wangEditor. The code changes reflect this update by
marking ueditor as '(不建议使用)' (not recommended) and WangEditor as
'(推荐使用)' (recommended). Additionally, the relevant controller file has
been updated to ensure that the correct default editor is loaded based on
the new configuration setting.
