EUA with GoCardless is valid for 180 days.

We can:

1. Anticipate that and set an EUA somewhere on the connected account
2. Handle the 401 response that we get when trying to sync an account with expired EUA:

{
  status: 401,
  statusText: 'Unauthorized',
  data: {
    summary: 'End User Agreement (EUA) xxxxxx-xxxx-xxxx-xxxx-xxxx has expired',
    detail: 'EUA was valid for 180 days and it expired at 2026-01-27 12:13:55.543011+00:00. The end user must connect the account once more with new EUA and Requisition',
    status_code: 401
  }
}

Based on that, the interface should have:

1. On the bank accounts list, update the account status to "Authorization Expired"
2. Add two columns: "Connected At" (= createdAt) and "Authorization validity" (∞ if none defined, the date otherwise)
3. Show an alert icon, with a tooltip message, next to this "Authorization validity" if it's expired or about to expire.
4. Send a notification email when it expires.
5. A clearer error message when clicking on "Force synchronize". It's currently an obscure 401 error.

All these should lead toward the Actions > Settings > Advanced > Reconnect action, to let host admins renew the authorization.
