halkyon_app: instances, sign-in and sync plumbing for Halkyon's apps
What every Halkyon app's shell needs, taken from Halkyon Learn's and set on halkyon_base's client: the instances a device keeps an account on, the first start's tiles and where an instance keeps people's data, the account switcher; signing in anonymously, with GitHub or an email code, switching person and the start screen; the gates that build an app's dependencies per instance and per person; and the sync service with its status, Settings card and banner. Texts of its own in English and German take the app's name; what only the app can say, it passes in. Fakes for apps' tests are in testing.dart. An instance's basics now name the app it serves (`app`, set by the host's configuration), and an app accepts only an instance of its own. SerialQueue and CoalescingRunner move into halkyon_core.
