реализовать отправление СМС через сервис

The issue mentions implementing an SMS sending service but provides no details on the provider, API, or integration points. Look for existing notification or communication modules in the Django backend. Research how SMS services are typically integrated (e.g., Twilio, other providers) and check the project's configuration files for related settings. Determine what 'done' looks like by finding where SMS notifications should be triggered, such as in manufacturing or safety alerts.
