Cross-reference: #35158 (where it currently looks like it doesn't work, necessitating this issue - or maybe they're separate/nuanced issues?)

[evq]

I'm going to reopen this as there are actually two cases and so far we've only solved the first one:

1. user is in active credentials state and request id reuse has not yet occurred ( my existing PR fixes )
2. user is in generated credentials state and request id reuse has already occurred ( user is forced to go through sign in )

After consulting with @husobee, we've decided that we will have the server return HTTP status 409 Conflict in the request id conflict case and modify the SDK to automatically regenerate the request id when this status code is returned.

The above requires 1.62.162 or higher for 1.62.x verification 👍
