Deploy to production / deploy (push) Has been cancelled
- Modified the deployment workflow to include new migration paths for the backend, ensuring that migrations are correctly referenced in the deployment process. - Updated the `db:migrate` script in package.json to point to the `migrations-active` directory, enhancing clarity and organization of migration files. - Adjusted the deployment conditions to account for changes in migration file locations, improving the accuracy of change detection during deployments. - Removed obsolete migration files to streamline the migration process and prevent confusion.
