Two Magic Link Emails Received on Continue Click (Sign in -> Continue) (PWA)

The sign-in process occasionally sends two magic links, back-to-back, where the links are different and the second one would likely invalidate the first one.

Something in the Continue button’s click handling could be creating a double-click operation internally. Something firing twice server-side could also lead to the double magic link message.

We should look at debouncing the button when clicked as a first step in ensuring the process isn’t triggered twice.

Screenshots showing the result where the magic links are different -- they're separate messages, not duplicate messages:

The initial step to resolve this issue is included with the PR for #1167, so we'll check in testing. Local testing has been successful.
