debug(push): add native push-setup telemetry to trace iOS registration

device_tokens stays empty after reinstall+Allow, so the APNs token is never
obtained or never reaches the server, and there's no device console on Windows.
Add a /api/push-debug collector and breadcrumbs through setupNativePush (plugin
presence, permission state, register call, registration event/error, token POST
result) so the failing step is visible in server logs. Temporary — remove once
push is confirmed.
