Title: Fix a few minor documentation and allocation problems in widgets.

* In `AnimationViewModel`, `clockViewModel` should be documented as required.
* In `HomeButtonViewModel`, document the default value for `flightDuration`.
* In `ClockViewModel`, avoid an unnecessary allocation of a `Clock` instance.
