web/flow: cleanup WebAuthn helper functions

[BeryJu]

Details

Remove utility functions we had as they are built in to the browser now

Requires #14461 to make sure nothing is broken, but local testing works fine

---

Seems like a lot of these APIs are only available on the latest Safari (18.4), which came out in late march...so we'll probably have to pull in this polyfill: https://github.com/MasterKale/webauthn-polyfills

---

Checklist

• Local tests pass (ak test authentik/)
• The code has been formatted (make lint-fix)

If an API change has been made

• The API schema has been updated (make gen-build)

If changes to the frontend have been made

• The code has been formatted (make web)

If applicable

• The documentation has been updated
• The documentation has been formatted (make website)
