Restore line break for partner email selection

[aduth]

🛠 Summary of changes

Updates layout of partner email selection screen to include a line break between "connected with:" line and the selected email, per the original design. This regressed in recent changes. It particularly affects cases where the user has not yet selected an email to be shared with the partner application.

📜 Testing Plan

Disable partner email selection feature before starting, in config/application.yml:

development:
  feature_select_email_to_share_enabled: false

1. Have sample application running in a separate process
2. Go to http://localhost:9292
3. Click "Sign in"
4. Create an account
5. Once returned to the partner, visit http://localhost:3000
6. Go to "Your connected accounts" page in account dashboard
7. Re-enable partner email selection feature by removing the config/application.yml added above, and restarting the local server
8. Refresh the "Your connected accounts" page
9. Verify "Email not yet selected" appears on its own line with "Change"
