v1.3.3 - Trails, Heatmap & Achievement Fixes

✨ New Features

• Aircraft Trails — Always-on tracking with altitude-colored segments
  • Altitude-based color gradient (green=low → red=high)
  • Dashed lines for missing/uncertain altitude data
  • Gap detection skips teleportation artifacts (>50km jumps)
  • Isolate button to focus on single aircraft trail
• Map Heatmap — Position density overlay showing traffic hotspots
  • Days selector (24h/7d/14d/30d)
  • Color legend (blue=low → red=high density)
• Regional & Bizjet Achievements — Now properly tracked with pre-computed counts
  • Regional: CRJ, ERJ, E-Jets, ATR, Dash 8, SAAB, Fokker
  • Bizjet: Gulfstream, Citation, Falcon, Learjet, Challenger, Hawker

🐛 Bug Fixes

• Version Display — Footer and update checker now pull from API instead of hardcoded
• Aircraft Rotation — Uses calc_track fallback when track heading unavailable
• Regional/Bizjet Achievements — Were stuck at 0 progress, now working
• Feed Status Stuck on "Checking..." — Removed stray code causing all feeds to show offline

🔧 Database Changes

• Added is_regional, is_bizjet columns to aircraft_summary
• Added regional_count, bizjet_count to stats_summary
• Auto-migration populates historical data on upgrade
