ENTERPRISE: Optimize system reliability and container deployment

Major improvements:
- Fix file manager paste operation timeout issues for small files
- Remove complex copyItem existence checks that caused hangs
- Simplify copy commands for better reliability
- Add comprehensive timeout protection for move operations
- Remove JWT debug logging for production security
- Fix nginx SSL variable syntax errors
- Default to HTTP-only mode to eliminate setup complexity
- Add dynamic SSL configuration switching in containers
- Use environment-appropriate SSL certificate paths
- Implement proper encryption architecture fixes
- Add authentication middleware to all backend services
- Resolve WebSocket timing race conditions

Breaking changes:
- SSL now disabled by default (set ENABLE_SSL=true to enable)
- Nginx configurations dynamically selected based on SSL setting
- Container paths automatically used in production environment
