feat(quick-260326-vn8): default type column to resourceConfig.typeUri in create method

- Add input['type'] = resourceConfig.typeUri after toHasuraInput in create()
- toHasuraInput strips the type field from request body (short name)
- Service layer now always sets the full canonical type URI for all resource types
- Add tests documenting the default type assignment contract in request.test.ts
