refactor(platform): rename ixp/ package to document_projects/

Name the design-time service folder after its domain entity rather than
the product acronym, matching the entity-based convention used elsewhere
in platform/ (connections, entities, documents, ...). Pairs cleanly with
the runtime sibling: documents/ (du_/api/framework) is DU runtime,
document_projects/ (du_/api/designtimeapi) is DU design-time.

The IxpDesigntimeService class name is unchanged (it names the API, not
the folder). Only the directory, the import path, and doc references move.
