Jakarta EE

- Use `@Transactional` for declarative transaction management. Implement `ExceptionMapper<T>` for consistent error responses. Use Bean Validation (`@NotNull`, `@Size`, `@Valid`) on DTOs. Use `@Produces`/`@Consumes` with `MediaType.APPLICATION_JSON`. Use `@Observes` for CDI event-driven communication between beans.
