Yared Yemane 73f11ea1a0 Content admin: course hierarchy, sub-categories API, and stability fixes
- Sub-categories: load from GET categories/:id/sub-categories; SubCategoryCoursesPage
- Course structure: levels/modules/sub-modules APIs; SubCoursesPage hierarchy browser
- Sub-module detail: HumanLanguageSubModulePage for category routes; resolveSubModuleForCourse
- Types and courses API: module sub-modules endpoint, hierarchy array guard
- Misc: AppLayout/IssuesPage fixes, CoursesPage refactor, Human Language hierarchy page
