fix(examples): permission and device testing fixes

- wifi_p2p/wifi_rtt: add ACCESS_WIFI_STATE permission
- usage: remove PACKAGE_USAGE_STATS (special permission, can't be
  runtime-requested — blocks app on permission dialog)
- alarm: remove SCHEDULE_EXACT_ALARM from runtime permissions (special
  permission on API 33+, blocks on dialog; example already handles
  canScheduleExactAlarms() == false gracefully)
- settings E2E test: mark as xfail (shell UID SecurityException)
- companion E2E test: upgrade from xfail to run (now passes on device)
