halkyon_app: instances, sign-in and sync plumbing for Halkyon's apps

Browse source 
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.

/// What every Halkyon app is built around, on an instance's halkyon_base:
///
/// - **Instances**: the ones a device keeps an account on, one in use at a
/// time (`InstanceChoice`), chosen at first start (`FirstStartScreen`) or
/// added later (`showAccountSwitcher`), each checked before the app moves
/// there (`InstanceChecker`) and saying where it keeps people's data.
/// - **Gates**: `InstanceGate` opens the app's dependencies on the instance
/// in use (`AppDependencies`, `AppScope`); `SessionGate` keeps a person
/// signed in and asks how to start once signed out (`StartScreen`);
/// `PersonScope` opens each person's own dependencies.
/// - **Signing in**: anonymously, with GitHub or with a code by mail
/// (`AuthRepository` on `ServerpodAuthGateway`), and the blocs and sheet
/// that switch a device to another account.
/// - **Sync**: `SyncService` on triggers, the changes still waiting, and
/// where it stands (`SyncStatusBloc`, `SyncStatusCard`, `AppMismatchBanner`,
/// `SyncTroubleBadge`).
///
/// An app gives its name, look and own words as an `AppFrame`, and installs
/// `HalkyonAppLocalizations.delegate` beside its own.
