### Description

`-[UIApplication statusBarOrientation]` is deprecated and a no-op as of iOS 27.

logs a deprecation warning to the console on every app launch.

The call site is `-[FIRCLSNotificationManager captureInitialNotificationStates]`,
invoked from `registerNotificationListener` as part of
`FIRCLSReportManager startCrashReporterWithProfilingReport:` during
`FIRCrashlytics` initialization.
