Walkthrough

The change removes the optimize: isImage option from a file upload call in WikiEditor.vue. This simplifies the upload configuration by relying on default optimization behavior instead of explicitly setting the option. No method signatures, variable names, or public APIs are affected. This is a minor configuration adjustment to the file uploader behavior.
