[PM-6761] Add fido credentials to data model

[Hinton]

Type of change

- [ ] Bug fix
- [x] New feature development
- [ ] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

Add Fido2Credentials to the Login struct to support storing passkeys. Currently we don't decrypt passkeys but rather pass them along encrypted to ensure we can re-encrypt the login without data loss.

Before you submit

• Please add unit tests where it makes sense to do so

Looks good from my perspective, but I'll let Dani make the final approval

❓ question: I'm curious why? Would it move somewhere else?

[Hinton]

Most likely you wouldn't expose this in the view. Instead you fetch the old entry from state and update values on it. That way you don't have to expose encrypted passkeys in the view.
