[Cells 1.0] Default Work Item Types: Check default work item type IDs on startup
- Ensure seeds and any existing migrations (also structure.sql) conform to constant default work item type IDs including a noisy error if not
- Ensure new installations conform to the "constant" constraint including Omnibus and GDK.
- Add a noisy error on startup if default work item types are not as expected, with link to the documentation on how to address.
