[PM-31614] Added new UI for the Email verification on sends

📔 Objective

Initial PR to add the layout changes for the Email Verification option on Sends.
The chagnes are behind a feature flag and should not have any impact when it is turned off.

This does not add the changes to the server and misses validations that will be added on subsequent PRs.
