refactor: enhance deployment cancellation logic and improve Railpack build isolation

- Reintroduced the `initCancelDeployments` function in the server initialization sequence to ensure deployments can be canceled effectively.
- Updated the Railpack build command to use a unique builder name for each build, preventing conflicts during concurrent deployments.
- Enhanced the cancellation logic to reset application and compose statuses to "idle" after canceling running deployments, improving system reliability.
