feat(teams): Use CoursesRepository in TeamCoursesFragment

Refactored TeamCoursesFragment to use CoursesRepository instead of direct Realm access.

- Injected CoursesRepository into TeamCoursesFragment's superclass.
- Added getCoursesByIds(ids: List<String>) method to the CoursesRepository interface and its implementation.
- Replaced the direct mRealm.where() call in setupCoursesList() with a call to the new repository method within a lifecycle-aware coroutine.
- Fixed a build error by removing a duplicate `coursesRepository` property that conflicted with the one inherited from `BaseResourceFragment`.

This change improves architectural separation of concerns and makes the fragment independent of the underlying data source implementation.
