rCOMM0350430166db: [shared] bump opaque-ke to 2.1.0-pre.1

Summary

This version of opaque-ke uses the latest version of voprf. The previous version of opaque-ke was using an older version of voprf that no longer works with the latest version of Rust. Hence, in order to upgrade to the latest version of Rust, we need to first upgrade opaque-ke.

As part of this upgrade, we need a wrapper for Argon2 that uses the default params from argon 0.4. Further explanation provided inline.

Basically copied this code: https://github.com/drey7925/perovskite/commit/2076604cb44ba9c103eb0208efa7449cfb34bb73#diff-400eb1f04580ae4870aa9d4aae3210268771ed3a5237703cc070d87296830d38

This resolves: https://linear.app/comm/issue/ENG-9164/upgrade-opaque-ke-20

Next diff will bump our Rust version from 1.76 to 1.82 (latest stable version)

deployed custom identity image to staging with these changes
checked out master branch
successfully logged in to existing account on staging identity from native, web, keyserver
successfully registered and logged in to staging from native
switched back to feature branch

realize there's Rust code so @ashoat isn't a good reviewer

23 ↗	(On Diff #45697)	These params come from this comment: https://github.com/facebook/opaque-ke/issues/359#issuecomment-2436428572 Basically, argon 0.5 uses different default params than 0.4. we need to use the 0.4 default params for existing users to be able to log in to identity

23 ↗	(On Diff #45697)	These params apparently represent the memory cost, time cost, and parallelism degree . Curious why increasing the time and memory costs caused this to break

Bitwarden did a similar thing recently: https://bitwarden.com/help/kdf-algorithms/#low-kdf-iterations maybe, but it would be a considerable amount of work. we'd have to re-register the user with the new params when they next log in and track which users have migrated to the new params. we'd also probably want to upgrade to opaque-ke v3 at the same time. IMO we shouldn't do this unless there's a real security risk. the opaque-ke maintainers didn't express any concerns with us keeping the same default params as before, so i think it's probably safe?
