This ticket completes the implementation of the the timer that counts down to when the one-time password expires. Now, we redirect to a page that informs users that their code has expired and to request a new one.

📜 Testing Plan

Provide a checklist of steps to confirm the changes.

Before testing

• add otp_valid_for: 3 to application.yml to speed up testing

1. Spin up application and log on to `http://localhost:3000
2. Create new account and follow steps for account creation
   1. On account creation, select phone and backup codes as MFA options for faster testing
3. Enter phone number to add to the account
4. On the one time password screen, wait approximately 30 seconds for the countdown banner to appear. The countdown will count down from the set otp_valid_for value
5. Wait until the timer reaches zero
6. Redirect to OTP expiration page
