fix(EMS-3348-3402): no PDF - check your answers - export contract - submit button

[ttbarnes]

Introduction ✏️

This PR fixes an issue where an unnecessary "save and back" button was rendering in the "Check your answers - export contract" page.

Resolution ✔️

• Remove unused EXPORT_CONTRACT_SAVE_AND_BACK UI route.
• Update E2E test.
• Update the GET controller's pageVariables to return a SUBMIT_BUTTON_COPY property instead of SAVE_AND_BACK_URL
  • Note: the submit button should have "save and back".
  • This is unique compared to all other "save and back" buttons, where they require a "save and back" URL.
  • This form now only has 1 button and is at the end of the "prepare application" section/journey.
• Update nunjucks template.
