[ttbarnes]

Introduction ✏️

This PR updates the "check your answers" functionality for the "Policy - Check your answers" form, to support the SELECT_THE_ADDRESS and FULL_ADDRESS fields, depending on if IS_BASED_IN_UK is true.

Note: This PR does include E2E coverage for changing the answer or the UK/non-UK differences. These will be added in the next PR.

Resolution ✔️

• Update checkPolicySummaryList E2E command.
• Add new check/change routes.
• Update field content strings.
• Update the following UI post controllers to redirect to CHECK_YOUR_ANSWERS if the URL is a "change" route:
  • Broker addresses
  • Broker manual address
• Add mapBrokerAddressBasedInTheUk helper function to the UI.
• Update policy summary list logic:
  • Create new brokerAddressField function.
  • Update optionalBrokerFields to call brokerAddressField.

Miscellaneous ➕

• Address some TODO comments.
• Minor documentation improvements.
