- kill_all() now resets gsm_spy_scanner_running and related state so
the scanner thread stops after killall
- scanner_thread sets flag to False instead of None on exit
- Restore alert_rules, alert_events, recording_sessions tables and
wifi_clients column removed by PR in database.py
- Escape all server-sourced values in analysis modals with escapeHtml()
- Reset gsm_towers_found/gsm_devices_tracked on stop to prevent
counter drift across sessions
- Replace raw terminate/kill with safe_terminate() in scanner_thread
