fix(editor): check parent MIME types to support subtype files in isMimeTypeSupport

- Retain QMimeType object to enable parent type lookup
- Add parentMimeTypes() fallback to match subtypes against whitelist

修复(editor): 在 isMimeTypeSupport 中检查父 MIME 类型以支持子类型文件打开

Log: 通过父 MIME 类型继承关系扩展白名单匹配范围，修复子类型文件无法打开的问题
