Add Missing REST API to Activate OIC Project Integrations/Deployments

Currently, there is no REST API available to activate integrations (deployments) within OIC Projects. This creates a major limitation for CI/CD automation, as deployments cannot be programmatically activated as part of a release pipeline.

Proposal:

• Provide a REST API endpoint to activate/deactivate OIC Project integrations and deployments.

Benefits:

• Enables full automation in CI/CD pipelines.
• Removes the need for manual activation steps.
• Increases reliability and consistency of deployment processes.
