Greg Pomerantz dc7661e226 Android: launch the 'All files access' settings screen at startup. ...

MANAGE_EXTERNAL_STORAGE (needed to read the store at
/storage/emulated/0/...) cannot be requested with a runtime
permission dialog; the user must toggle it in system settings.
Port the mechanism from the pad app:

- Permissions.java: a Fragment registered at window attach that
  launches Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION
  (per-app settings screen) when Environment.isExternalStorageManager()
  is false on API 30+ (runtime READ_EXTERNAL_STORAGE request on
  older APIs). The guard means the screen appears only until the
  user grants it.
- The compiled classes ship in PgpConnect.jar's directory jar
  (Permissions.jar); gogio picks *.jar up from the package dir and
  dexes them. go:generate now rebuilds it.
- jni_android.c/h: registerPermissionsFragment(), mirroring
  registerFragment() for PgpConnect.
- Impl wiring: call it from the AndroidViewEvent handler right
  after InitPgp.

Verified on the x86_64 emulator: with the appop denied the system
settings screen opens automatically on launch; after granting it,
launch is clean and list + OpenKeychain decryption from
/sdcard/Pass work end to end.
