Update LDM-148 DM design

The text has been synchronized with the product tree in MagicDraw (including the restoration of the Prompt Processing service), as has the MagicDraw-generated deployment diagram. The Middleware diagram has been updated to reflect PipelineTask terminology, and Batch Production Services and the Data Backbone have been separated from Middleware in the text. LSE-400 has been added to the interface requirements, and the tracing table has been updated to reflect new and removed requirements and components.
