The fetchRelatedLessons function provide related lessons for a specific content item,constructing a dynamic query that accounts for multiple relationship scenarios and sorting rules. Here’s a breakdown of how the related lessons are fetched and organized:

• Child Lessons: Lessons that are direct children of the specified content (railContentId). These lessons are fetched with metadata like title, difficulty level, artist, and permission IDs.

• Lessons by Artist (Same Type): Songs of the same type and brand where the artist matches that of the specified content. The lessons exclude the current railContentId and are ordered by published_on (descending) and title (ascending). The result is limited to 10 lessons.

• Lessons by Genre (Same Type): Songs of the same type and brand where the genre matches that of the specified content. These lessons are also ordered by published_on (descending) and title (ascending), excluding the current railContentId and limited to 10 results.

• Same Type with Custom Sort (by episode number): Lessons of the same type, where the type is listed in a predefined set (typeWithSortOrder). These lessons are sorted by the custom sort field (ascending), followed by title (ascending), limited to 10 results.

• Same Type with Default Sort (by published-on): Lessons of the same type, but not in the typeWithSortOrder list. These are sorted by published_on (descending) and title (ascending). The result is limited to 10 lessons.

Each related lesson type is fetched uniquely and combined using array::unique to prevent duplicates. The total number of related lessons is limited to 10.
