fix: Update expiration timeline on dashboard and specify ID verification (#27199)

MST-706. ID Verification is now valid for 2 years, so messaging used to notify learners about their ID expiration should be updated to reflect this. We have chosen to only update the messaging that is related to the current IDV flow (going through IDV on the account MFE), as the old IDV flow is no longer used by learners on edX.
