EL-1048: Refactor check answer screen to use cards

[patrick-laa]

Jira ticket

What changed and why

The check answers screen now uses cards
The yaml file now defines how 'add another' works, both for adding another card and adding another field within a card
The yaml file also fully defines when to show the disputed asset tag
Check answers 'Change' links to add another screens now have anchors to the appropriate section on the page
The system for anchors back to the check answers screen is now much simpler and doesn't need a separate service to define anchor IDs.
