Add TSCM counter-surveillance mode (Phase 1)

Features:
- New TSCM mode under Security navigation group
- Sweep presets: Quick, Standard, Full, Wireless Cameras, Body-Worn, GPS Trackers
- Device detection with warnings when WiFi/BT/SDR unavailable
- Baseline recording to capture environment "fingerprint"
- Threat detection for known trackers (AirTag, Tile, SmartTag, Chipolo)
- WiFi camera pattern detection
- Real-time SSE streaming for sweep progress
- Futuristic circular scanner progress visualization
- Unified threat dashboard with severity classification

New files:
- routes/tscm.py - TSCM Blueprint with REST API endpoints
- data/tscm_frequencies.py - Surveillance frequency database
- utils/tscm/baseline.py - BaselineRecorder and BaselineComparator
- utils/tscm/detector.py - ThreatDetector for WiFi, BT, RF analysis

Database:
- tscm_baselines, tscm_sweeps, tscm_threats, tscm_schedules tables
