Wires the "Install vX.Y.Z" action the About card's update-check
teed up.
* ApkInstaller @Singleton — downloads the server APK via the shared
OkHttpClient (inherits auth cookie + BaseUrlInterceptor host
rewrite; apkUrl is server-relative) into cacheDir, then launches
the system installer via a FileProvider content:// URI. canInstall()
gates on PackageManager.canRequestPackageInstalls() on O+, and
requestInstallPermission() opens the "install unknown apps" settings
page when not yet granted.
* Manifest: REQUEST_INSTALL_PACKAGES permission + FileProvider
(${applicationId}.fileprovider) + res/xml/file_paths.xml exposing
the cache dir.
* AboutCardViewModel.install(info): permission check → download →
launch, with isInstalling + installMessage state. Errors routed
through ErrorCopy.
* About card shows an "Install vX.Y.Z" button under the check button
when an update is available, "Downloading…" while in flight, and
the install message line. Extracted UpdateControls / InstallButton /
ButtonSpinner helpers to keep AboutCard under the length cap;
added @file:Suppress(TooManyFunctions) for the settings-card density.
Closes audit v3 #25 — the last open parity item from the v3 sweep
aside from the offline-pool Home cards (#28).
