fix(editor): support opening files with MIME subtypes via parent type inheritance

- Refactor isMimeTypeSupport() to retain QMimeDatabase and QMimeType objects for further queries
- Replace QStringList stream insertion with initializer list construction
- Add parentMimeTypes() lookup to match MIME subtypes against the whitelist (e.g. application/schema+json → application/json)

修复(editor): 通过父类型继承支持打开 MIME 子类型文件

- 重构 isMimeTypeSupport()，保留 QMimeDatabase 和 QMimeType 对象以供后续查询
- 将 QStringList 的流插入替换为初始化列表构造
- 新增 parentMimeTypes() 查找，将 MIME 子类型与白名单匹配（如 application/schema+json → application/json）

Log: 修复 JSON Schema 等 MIME 子类型文件无法被编辑器打开的问题，通过检查父 MIME 类型继承关系扩展白名单匹配范围
