Error: There is no container instance that can be provided to this Durable Object, try again later

## Issue Summary

Container instances are not available on production Cloudflare Workers account, causing all container-related operations to fail with error: "There is no container instance that can be
provided to this Durable Object, try again later"

## Environment Details

- Account: Production Cloudflare Workers account (can share per request)
- Wrangler Version: 4.23.0
- Container Config: instance_type: "dev" with @cloudflare/containers SDK
- Deployment: Working locally and in tutorial examples, failing in production

## Error Details

ERROR: There is no container instance that can be provided to this Durable Object, try again later

Configuration wrangler.jsonc:
```json
{
"containers": [{
"name": "code-container",
"class_name": "CodeContainerDO",
"image": "./Dockerfile",
"instance_type": "dev"
}],
"durable_objects": {
"bindings": [{
"class_name": "CodeContainerDO",
"name": "CODE_PORTABLE"
}]
}
}
```

Steps to Reproduce

1. Deploy worker with container configuration
