Update PulseResponse object

[mkimberlin]

As a System Administrator I want the PulseResponseController to return and accept objects with internalScore and externalScore fields in addition to the existing ones, so that pulse survey responses can capture scores for internal and external feelings.

Acceptance Criteria:

• The PulseResponse entity class should be updated to include internalScore and externalScore fields (data type: integer).
• The PulseResponseController service methods should be modified to:
  • Accept PulseResponse objects with the new fields during creation.
  • Return PulseResponse objects with the new fields during retrieval.
  • The updatedDate field should be removed from the PulseResponse entity as well as any references to it.
• Tests are updated to ensure these changes are reflected and that the endpoints handle these fields appropriately.
