## Summary
- Removes the `workspaceId` column, `@Index()`, and `@ManyToOne`
workspace relation from `BillingSubscriptionItemEntity`
- The entity defined these fields but they don't exist in the actual
database table, causing `column X.workspaceId does not exist` errors at
runtime
- The workspace relationship is already accessible through the parent
`BillingSubscriptionEntity`
