Please select the aspect the issue is related to

Aspect/API (API backends, definitions, contracts, interfaces, OpenAPI)

Description

When you delete an API from the Platform Gateway, it is correctly removed from the router, and the API no longer accepts requests. However, when you check the Policy Engine config_dump, the routes for the deleted API are still present.

Steps to Reproduce

1. Start the platform gateway independently with config_dump enabled
2. Create a sample API
3. Observe the API is responding
4. Delete the API
5. Observe the API is not responding
6. Goto http://localhost:9002/config_dump and observe the dangling routes of the deleted API
