prober: fix three bugs exposed by the first device report (OnePlus 15/A16)

- AndroidManifest: add CHANGE_NETWORK_STATE — requestNetwork threw
  SecurityException, multinetwork.request_and_bind could never run.
- IcmpProbe: format rtt_ms with Locale.ROOT — Austrian locale produced
  "38,1" in the JSON report.
- ShizukuRunner/ShizukuProbe: bind the UserService once per battery
  (execBatch) instead of per command; the per-command bind/unbind raced
  Shizuku and 3/7 commands died on SHIZUKU_BIND_TIMEOUT.

Archive the report at echolot-prober/reports/, record findings in
build-status.md. Notable: errqueue path fully reachable on Android 16 —
the native shim may be unnecessary on modern devices.
