feat: Integrate frequency-based device identification system

Integrated comprehensive device attribution system into GigLez: 1. Simple Device Matcher (src/matcher/simple_matcher.py): - Frequency-based device categorization (315/433/868/915 MHz) - Protocol-specific identification (Princeton, EV1527, Oregon Scientific, etc.) - Modulation + frequency matching (OOK/FSK/ASK) - Confidence scoring (0.4-0.95 range) - 50+ device types covered 2. API Integration (src/api/main_simple.py): - Device matching in upload pipeline - Added device fields: device_name, device_category, match_confidence, match_method, device_description - Top 5 alternative matches stored per capture - New endpoint: GET /api/v1/captures/{id} for detail view 3. Frontend Implementation: - Detail modal with comprehensive device information - Device identification section with confidence bars - Alternative matches display - Signal, location, and metadata sections - Keyboard (ESC) and click-outside modal closing 4. UI Enhancements (static/css/main.css): - Modal overlay with backdrop blur - Animated modal slide-in - Confidence visualization (green/yellow/red bars) - Responsive detail grid layout - Device match cards with categories 5. JavaScript Integration: - detail-modal.js: Comprehensive detail view renderer - Updated map.js and search.js to use detail modal - Removed placeholder functions 6. Utilities: - scripts/rematch_captures.py: Re-run matcher on existing data - Successfully re-matched 20 existing captures Device Categories Supported: - Consumer RF (remotes, sensors) - Automotive (key fobs, TPMS) - Home Automation (garage/gate openers, blinds) - Sensors (weather stations, temperature) - Security (door/window sensors, alarms) - IoT (smart meters, LoRa devices) - Industrial (SCADA, telemetry, RFID) Match Methods: - Protocol matching (highest confidence: 0.7-0.95) - Frequency matching (0.4-0.7) - Modulation + frequency matching (0.5-0.7) Frontend now displays: - Device name and category on map markers - Confidence percentage - Detailed device information modal - Alternative device matches - Match method explanation All existing captures successfully identified with 60-70% confidence.
