Fix verification failed issue, simplify verification logic (#3830)

* Simplify session verification:

- Reuse Rust `Client` instances created on the login process so we don't need to restore one right before the session verification.
- Remove unnecessary sources of verification state updates.
- Add an intermediate FTUE flow step which will display an indeterminate progress indicator instead of a blank screen.

* Remove unnecessary workaround: the SDK should already handle this

* Add regression tests for noop analytics service usage.

* Add `services.analytics.noop` module to the test dependencies
