chore: Add businessId to Instance model

Updated the Instance model to include a new optional string property called businessId. This change affects the following files:

- prisma/postgresql-schema.prisma
- src/api/controllers/instance.controller.ts
- src/api/dto/instance.dto.ts
- src/api/services/monitor.service.ts
- src/validate/instance.schema.ts

A new untracked migration folder has been created to manage database schema updates:

- prisma/migrations/20240712144948_add_business_id_column_to_instances/

This change allows for storing a business identifier alongside the instance, enhancing the ability to categorize and manage instances more effectively.
