feat: complete project organization and essential files

Add essential development files and complete structural cleanup:

* Create comprehensive .env.example template
- Organized by sections with clear documentation
- Covers all configuration aspects: security, APIs, database, monitoring
- Includes optional features and development settings
- Provides guidance for different deployment scenarios

* Clean up outdated directories
- Remove obsolete /apps/ directory
- Maintain clean project structure

Project organization improvements:
- Essential configuration templates in place
- Clear development setup guidance
- Reduced project complexity and maintenance overhead
- Better developer onboarding experience

The project now has a professional, well-organized structure
ready for production deployment and team collaboration.
