The scanner and monitor are mutually exclusive (both need the SDR).
Previously auto-monitor tried to start mid-scan (causing device
conflicts) and required 3 towers (rarely achieved with weak signals).
Now after the first scan completes:
- If any towers were found, automatically stop scanner and start
grgsm_livemon + tshark on the strongest tower's ARFCN
- SDR handoff is clean (scanner process has already exited)
- If monitor fails to start, scanner loop resumes
- Scanner thread's finally block preserves SDR allocation when
monitor has taken over
- Frontend shows "Monitoring ARFCN X for devices..." status

- Forward scanner progress (%) and status to SSE stream
- Show progress bar and scan status in TRACKED TOWERS panel
- Send scan_complete event with tower count and duration
- Fix Europe BAND_CONFIG: only EGSM900 is recommended (GSM850/GSM800
are rarely used in Europe and waste scan time)
- DCS1800 available but not recommended (RTL-SDR sensitivity is lower)

Backend:
- Filter out CID=0 and MCC=0 entries (ARFCNs with no decoded cell identity)
Frontend:
- Move stats update before coordinate check so towers always counted
- Fix signal_strength display using null check instead of || (0 is falsy)
- Show operator name, frequency, and status in tower detail panel
- Show "Located" indicator in tower list for geocoded towers
- Fix selectTower crash when tower has no coordinates
- Update placeholder text to "Select a tower from the list"
- Add try/catch to selectTower for error resilience
Tests:
- Add tests for CID=0 and MCC=0 filtering

- Send all existing towers on SSE connect (fixes data loss on reconnect)
- Fix tower.signal -> tower.signal_strength field name in frontend
- Fix TypeError crash in selectTower when tower has no coordinates
- Add Connection: keep-alive header to SSE response
- Add comprehensive console.log debugging for SSE data flow
- Handle error/disconnected SSE event types in frontend

UI was sending GSM900 but backend REGIONAL_BANDS expects EGSM900
for Europe and Asia regions, causing validation rejection.

- 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
