feat: Add winctl.sh management script and multi-version setup

Add winctl.sh with 12 commands for managing Windows Docker containers:
- start, stop, restart, status, logs, shell, stats
- build, rebuild, list, inspect, monitor, check
- Interactive menus, prerequisites checking, color output
- Support for 22 Windows versions across 4 categories

Multi-version compose structure:
- Split base.yml into base-modern.yml (8G) and base-legacy.yml (2G)
- Add .env.example for configuration
- Update all compose files to use env_file
- Add unique port mappings per version
- Update README with winctl.sh documentation
