Toggles the completion status of a todo item within a project component item. Updates the isDone status, sets doneBy to the current user, and updates doneUpdatedAt timestamp. This endpoint uses the processComponentsTodos permission, allowing users to toggle todo completion without requiring full component management permissions. After toggling, the system recalculates conditions and marks the project configuration as changed.
