[MST-1065](https://openedx.atlassian.net/browse/MST-1065)
When the Name Affirmation feature is enabled, a few panels in the IDV workflow should have different copy to reflect the changes associated with Name Affirmation. This is because entering a new during the IDV flow (GetNameIdPanel) will no longer modify the learner's "Account Name". Furthermore, "Account Name" is an ambiguous term; it's not clear that it refers to the learner's full name on their profile. These copy changes make the panel more generic and remove details about name changes. The SummaryPanel also has a minor copy change to change "Account Name" to "Name".
These code changes also include some UI changes.
