feat(sms): implement SMS messaging and metered billing

Implement a complete SMS messaging system including: - Integration with SMS Manager.cz API for sending messages. - Metered billing via Stripe using monthly aggregate invoice items. - Backend services for managing SMS settings, usage logging, and monthly reporting. - Database migrations for tenant settings, usage logs, and monthly reports. - Frontend dashboard components for SMS configuration, usage tracking, and history. - Support for customer phone numbers in the booking flow. Includes new migrations, backend services, and frontend UI components.
