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.
