Removes one or more users from the follower list of the specified entity. Once removed, these users will no longer
receive notifications about updates, comments, or status changes for the entity. This operation is useful for
managing notification lists and removing users who no longer need to track specific entities.

Key Features:

• Supports bulk removal of multiple followers in a single request
• Validates user IDs before processing removal
• Gracefully handles cases where users are not currently followers
• Automatically converts user GUIDs to internal format for processing

Authorization Logic:

1. User must have a valid JWT token with appropriate scopes
2. Token is valid for this operation
3. User must have permission to manage the target entity
4. Users can typically remove themselves as followers with view permissions

Usage Example:

Remove team members from following a completed program to reduce notification noise.

Success Response:

Returns 204 No Content when followers are successfully removed. No response body is included.
