fix: enhance CI/CD pipeline with robust import strategy and lifecycle management

- Add comprehensive resource import strategy for services, deployments, and secrets
- Fix group service DNS issues by adding group service alias
- Add lifecycle management to prevent Kubernetes metadata drift
- Fix GenAI service references to use simple service names
- Add post-deployment validation and health checks
- Remove redundant ignore_changes warnings
- Create manual import script for testing

This resolves 'already exists' errors in CI/CD and ensures zero-downtime deployments.
