Extends the existing ApiExceptionHandler @RestControllerAdvice to map DateTimeParseException and IllegalArgumentException to 400 Bad Request. Logs and agent-events endpoints both parse ISO-8601 query params and previously leaked parse failures as internal server errors. All IllegalArgumentException throw sites in production code are input-validation usages (slug validation, containerConfig validation, cursor decoding), so mapping to 400 is correct across the board.
