Add interactive Base 4 track map with Leaflet.js

- Created new track-map page with aerial image and SVG overlay
- Implemented custom rotated square markers with obstacle numbers
- Added admin edit mode for placing and repositioning markers
- Database migration for track_obstacles table
- Modal form for adding new obstacles (replaces browser alerts)
- Drag-to-reposition functionality with auto-save
- Color-coded markers (green/red/black/split) for difficulty levels
- Clickable popups showing obstacle details
- Added track-map to navigation menu and sitemap
- URL rewrite rule for clean /track-map URL
