app: tell the user before the run when Shizuku is installed but not started

Distinguishes not-installed (say nothing — don't nag users who don't use
Shizuku) from installed-but-stopped (amber banner: start it to include
shell-tier tests), plus running-unauthorised and ready. Detection is
listener-based since pingBinder() only becomes truthful once
ShizukuProvider delivers the binder; a launch-time poll would show a false
"not running". Installed-vs-not needs the <queries> entry on Android 11+.

Verified on-device: with shizuku_server stopped, the banner shows before
pressing Run; the title also now clears the status bar/cutout after the
safeDrawingPadding fix.
