Final cleanup: Complete Flask motorcycle adventure app

- Removed all Node.js/Next.js dependencies and files
- Cleaned up project structure to contain only Flask application
- Updated .gitignore to exclude Python cache files, virtual environments, and development artifacts
- Complete motorcycle adventure community website with:
  * Interactive Romania map with GPX route plotting
  * Advanced post creation with cover images, sections, highlights
  * User authentication and authorization system
  * Community features with likes and comments
  * Responsive design with blue-purple-teal gradient theme
  * Docker and production deployment configuration
  * SQLite database with proper models and relationships
  * Image and GPX file upload handling
  * Modern UI with improved form layouts and visual feedback

Technical stack:
- Flask 3.0.0 with SQLAlchemy, Flask-Login, Flask-Mail, Flask-WTF
- Jinja2 templates with Tailwind CSS styling
- Leaflet.js for interactive mapping
- PostgreSQL/SQLite database support
- Docker containerization with Nginx reverse proxy
- Gunicorn WSGI server for production
