Implement SQLite database for wssshd2 web interface user management

- Add SQLite support with proper database initialization
- Create users table with id, username, password_hash, is_admin columns
- Implement user management functions (add, update, delete, find)
- Add security warning for default admin credentials
- Add ASCII art banner on startup
- Fix login/logout redirects to home page
- Add --debug-database option for database operations logging
- Support root user directory selection (/etc/wssshd vs ~/.config/wssshd)
- Generate dynamic user management interface
- Maintain compatibility with existing web interface features
