Updates the display order (rank) of a task, request, or program by repositioning it relative to another item.
The rank determines the default sort order when viewing items in lists. This endpoint uses a lexicographic
ranking system that efficiently handles reordering without requiring updates to all other items in the list.

Key Features:

• Reorder tasks, requests, or programs within their parent container or list view
• Position items before the first item or after any specific item using nodeIdAfter
• Uses efficient lexicographic ranking that doesn't require updating all items
• Updates are immediately reflected in list views sorted by rank
• Maintains rank consistency across all users viewing the same space

Authorization Logic:

1. User must have a valid JWT token with management scopes
2. Token must be valid for this operation (tenant tokens are not supported)
3. User must have permission to update the entity being reordered

Usage Example:
Drag and drop a task to reorder it in a task list, move a program to prioritize it in the program view,
or reposition a request to organize workflow priorities.
