chore(ping-service, build): remove local SecurityConfiguration, update Dockerfile, and adjust application.yaml

- Deleted `SecurityConfiguration.kt` in favor of centralized security standardization.
- Optimized `Dockerfile` by replacing missing frontend directories with dummy paths for improved build stability.
- Updated `application.yaml` with updated default Keycloak and Postgres configurations.
