[flexiglass] Improvements to lockout state management and rendering:

1. Add a new flow `failedAuthenticationAttempts`, which is updated
directly from the upstream source of truth. This will be needed for the
device wipe dialog, so needs to be independent from lockout.

2. Remove the `lockout` state and associated model, which is now
redundant; we store the lockout end timestamp and failed auth attempts
as separate and independent pieces of state.

3. Unify `setLockoutDuration` with `reportLockoutStarted`.

4. Move the lockout countdown updates to the view-model, because it is a
transient state that is only relevant for presentation (UI message) and
so we can shave off some propagation overhead and complexity.

5. Fix bug where the throttling dialog countdown is updating every
second (it should remain constant).

6. Fix bug where the lockout dialog would be shown again when switching
to a user with an active lockout.

7. Make `AuthenticationRepository` responsible for maintaining the
freshness of the `hasLockoutOccurred` state.

8. Rename `authenticationChallengeResult` to `onAuthenticationResult`,
to convey it's a flow of events rather than state (similar to our
de-facto convention elsewhere), and move it out of the repository.

9. Refactor `AuthenticationInteractorTest` to be more concise, readable
and robust.
