Describe the bug

Discovered during debug of issue reported in ticket: https://avni.freshdesk.com/a/tickets/3786

We use program.name and encounterType.name values in DEA, which is confusing to the end-user who expects them to instead show program.operationalProgramName and encounterType.displayName respectively, similar to the way its handled in client.

Acceptance Criteria

• We should show Program operationalProgramName in EncounterTypes List view.
• We should use encounterType.displayName while creating Program or General Encounters from webapp
