Summary

This PR picks up the automated API client update from 717f3b1 (Update API Client, July 14) and fixes the hand-written SDK code that broke as a result of two breaking changes in the
regenerated client:

1. IntegrationName renamed to IntegrationProvider

The upstream OpenAPI spec renamed the IntegrationName enum to IntegrationProvider (file integration_name.py → integration_provider.py, LABELSTUDIO value also removed). Updated all references
in:

• src/splunk_ao/integration.py
• src/splunk_ao/provider.py
• src/splunk_ao/resources/models/init.py
• tests/test_integration.py

2. type_ removed from ProjectUpdate

The new spec dropped type_ from the ProjectUpdate model. Updated:

• src/splunk_ao/project.py — removed type_=self.type from the ProjectUpdate constructor call and the corresponding response attribute sync
• tests/test_project.py — removed the updated_response.type_ = RESOURCES_UNSET setup that is no longer valid

Testing

All 1819 tests pass locally (invoke test-report-xml). Type check clean (invoke type-check).
