Initial commit: Fleet Management app with security hardening and background launcher

- Flask app with SQLAlchemy, Flask-Login, Flask-Mail
- Admin/owner roles, vessel management, charters, work orders
- Background launcher (Iniciar.vbs) runs server without terminal window
- Root redirect fixed: / → /login
- debug=False, use_reloader=False for pythonw.exe compatibility
