- Replaced local `SecurityConfig` in `ping-service` with the shared `infrastructure:security` module. - Added `GlobalSecurityConfig` to standardize OAuth2, JWT validation, and CORS for all services. - Introduced new endpoints (`/ping/public`, `/ping/secure`) with role-based access control. - Updated database schema with Flyway migration (`V1__init_ping.sql`) and refactored persistence layer to align with the standardized approach (`createdAt` field). - Enhanced application configuration (`application.yaml`) to use shared security and Flyway settings.
