Merge Testing and Integration Tests into a single Testing control center in AdminSettings. Remove the separate integration-tests tab, and update the Testing tab to render both Test Data Generator and Integration Test Runner together, with appropriate headers and icons (Database and TestTube). Add Database to imports.
Implement the destructive migration plan to remove the old approval flow entirely. This includes deleting the legacy edge function, removing the toggle component, simplifying frontend code, and updating documentation.
Implement blue-green deployment strategy for approval flow. This involves deploying the new RPC function alongside the existing edge function, creating a new edge function that calls the RPC, and adding a feature flag to the frontend to toggle between the old and new flows. The plan includes testing in production, gradual rollout, and eventual deprecation of the old edge function.
