The monitored tower may have CID=0 (partially decoded cell) which
OpenCellID can't geocode, leaving it without coordinates. The heatmap
now falls back through: monitored tower by ARFCN, any geocoded tower,
then observer location. Also tracks the monitored ARFCN so the fallback
can find the right tower even when CID matching fails.

The heatmap silently failed when: CID types mismatched (string vs number),
LAC wasn't checked (wrong tower matched), or no data existed yet (button
showed ON with no layer). Now coerces CID/LAC to Number for comparison,
validates coordinates with parseFloat, logs match diagnostics to console,
and only shows ON when the layer is actually rendered.

Adds a toggleable heatmap layer that visualizes crowd density data from
the existing /gsm_spy/crowd_density endpoint as a gradient overlay on the
map, with auto-refresh every 30s during active monitoring.

Add explicit band name mapping from internal names to grgsm_scanner's
accepted -b values (GSM900, GSM850, DCS1800, PCS1900). Bands without
a valid grgsm_scanner equivalent (GSM800, EGSM900_EXT) are skipped
with a log message instead of crashing the scanner. Remove GSM800
from the dashboard band selector since it can't be scanned.

Wire SIGNALS/DEVICES/CROWD counters to monitor_heartbeat SSE data so
they update in real-time during monitoring. Redesign device list items
as richer cards with type badges, TA/distance, and observation counts.
Add clickable device detail modal with full device info and copy
support. Improve tower list with signal strength bars. Widen right
sidebar and bump list font sizes for readability.

Backend: monitor_thread sends periodic monitor_heartbeat events (every
5s) with elapsed time, packet count, and device count so the frontend
knows monitoring is active.
Frontend: new monitoring overlay replaces scan progress bar when
auto-monitor starts. Shows pulsing green indicator, ARFCN being
monitored, live elapsed timer, packet/device counts, and
"Listening..."/"Capturing" activity state.

- Repositioned progress indicator from right sidebar to a full-width
overlay at the top of the map panel
- Added animated spinning icon, glowing progress bar, blurred backdrop
- Centered layout with max-width constraint for readability
- Progress bar and status text more visible during active scans

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
