feat: Add wifi-Mat disaster detection enhancements

Implement 6 optional enhancements for the wifi-Mat module:

1. Hardware Integration (csi_receiver.rs + hardware_adapter.rs)
   - ESP32 CSI support via serial/UDP
   - Intel 5300 BFEE file parsing
   - Atheros CSI Tool integration
   - Live UDP packet streaming
   - PCAP replay capability

2. CLI Commands (wifi-densepose-cli/src/mat.rs)
   - `wifi-mat scan` - Run disaster detection scan
   - `wifi-mat status` - Check event status
   - `wifi-mat zones` - Manage scan zones
   - `wifi-mat survivors` - List detected survivors
   - `wifi-mat alerts` - View and acknowledge alerts
   - `wifi-mat export` - Export data in various formats

3. REST API (wifi-densepose-mat/src/api/)
   - Full CRUD for disaster events
   - Zone management endpoints
   - Survivor and alert queries
   - WebSocket streaming for real-time updates
   - Comprehensive DTOs and error handling

4. WASM Build (wifi-densepose-wasm/src/mat.rs)
   - Browser-based disaster dashboard
   - Real-time survivor tracking
   - Zone visualization
   - Alert management
   - JavaScript API bindings

5. Detection Benchmarks (benches/detection_bench.rs)
   - Single survivor detection
   - Multi-survivor detection
   - Full pipeline benchmarks
   - Signal processing benchmarks
   - Hardware adapter benchmarks

6. ML Models for Debris Penetration (ml/)
   - DebrisModel for material analysis
   - VitalSignsClassifier for triage
   - FFT-based feature extraction
   - Bandpass filtering
   - Monte Carlo dropout for uncertainty

All 134 unit tests pass. Compilation verified for:
- wifi-densepose-mat
- wifi-densepose-cli
- wifi-densepose-wasm (with mat feature)
