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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
