- Add PING endpoint to SafeEatsEndpoint enum - Create NetworkInfo utility for network type, cellular generation, and carrier detection - Create PingRepository for measuring backend latency - Integrate ping call after successful login (once per app lifecycle) - Add trackEdgePing() to Analytics for PostHog logging - Add comprehensive logging throughout ping flow - Log latency and metadata (app_version, device_model, network_type, cellular_generation, carrier) to PostHog The ping endpoint is called non-blocking after device registration completes. All metadata is collected and logged to PostHog with event name 'edge_ping'.

- Remove detailed debug logging from NetworkInfo, PingRepository, LoginAuthViewModel, and Analytics - Keep essential error logging for debugging failures - Clean up code for production readiness
- Replace SharedPreferences persistence with in-memory @volatile flag - Ping flag now resets on app restart (true once-per-lifecycle behavior) - Remove KEY_PING_CALLED from AppConstants (no longer needed) - Remove ping flag preservation logic from signOut methods Previously, the ping flag persisted across app restarts via SharedPreferences, causing ping to be skipped on every subsequent app launch after the first. Now the flag is stored in-memory only and resets when the app process restarts.
