Configure OpenAPI for complex nested type schemas

Update Startup.cs OpenAPI configuration to handle deeply nested types:

- Add CreateSchemaReferenceId callback to use simple type names,
  reducing schema complexity and improving readability
- Increase JsonSerializerOptions.MaxDepth to 256 to accommodate
  complex nested ViewModels during schema generation
- Change OpenAPI endpoint path to /api/openapi/{documentName}.json
  to avoid conflicts with static files in wwwroot/openapi/

These changes allow runtime OpenAPI generation to complete successfully
for all 164 API endpoints without hitting depth limits or memory issues.

Note: Runtime generation requires ~4GB RAM due to complex schema
processing. Static files are still served for production use.
