GPS geolocation only works on HTTPS or localhost. Added manual lat/lon
input fields so users can enter their coordinates directly when
accessing the app over HTTP on a local network.

New features for both ADS-B tab and dashboard:
1. Range Rings - Concentric circles at 25, 50, 100, 150, 200nm showing
distance from observer location with dashed styling and labels
2. Statistics Panel - Tracks:
- Max range achieved (with aircraft that achieved it)
- Total unique aircraft seen this session
- Messages per second rate
- Busiest hour of tracking
3. Geolocation Button - Gets user's actual GPS location to:
- Center the map on their position
- Calculate accurate distances for range statistics
- Position range rings correctly
4. Reception Statistics - Real-time msg/sec counter to monitor
receiver performance
All features work on both the ADS-B tab and full-screen dashboard.

The UK range 0x400000-0x43FFFF was the entire UK allocation, not just
military - this incorrectly flagged civilian airlines like EasyJet
(EZY callsign) as military aircraft.
Fixed ranges:
- Removed broad UK range, kept only RAF sub-range 0x43C000-0x43CFFF
- Narrowed France range to actual military 0x3F4000-0x3F7FFF
- Fixed Germany to correct Luftwaffe range 0x3D0000-0x3DFFFF
- Fixed typo in US range (0xADFFFFF -> 0xADFFFF)

Use requestAnimationFrame to throttle expensive rendering operations.
Previously every SSE message triggered full UI re-renders causing
browser unresponsiveness with 50+ aircraft.
