Fix Interactive Route Map: Create MapRoute records from GPX files

- Create MapRoute database records for all GPX files for map visualization
- Populate route statistics (distance, elevation, coordinates) from GPX parsing
- Update GPX file statistics to mirror MapRoute data for post detail pages
- Enable /community/api/routes endpoint to return proper route data for map iframe
- Fix post detail page GPX statistics display

This resolves the issue where the community map showed '2 routes discovered'
but routes weren't actually rendering on the Leaflet.js map visualization.

Changes:
- Dockerfile: Updated init script paths and added migrate-db call
- app/__init__.py: Added admin user auto-creation with error handling
- app/routes/community.py: Added debug logging and API route for map data
- docker-compose.yml: Simplified to use .env for environment variables
- run.py: Added comprehensive database schema migration command
