ECS Service Creation Stuck Due to No Available Container Instances

## Checklist

* [x] Upgrade UFO: I am using the latest version of UFO.
* [x] Reproducibility: This is a reproducible bug.
* [x] Code sample: Included below.

## My Environment

| Software | Version |
| ---------------- | --------------------- |
| Operating System | macOS / WSL (Windows) |
| UFO | Latest |
| Ruby | 3.3.0, 3.2.2 |

## Expected Behaviour

The `ufo ship` command should deploy the ECS service without any issues, creating the necessary ECS cluster and running the tasks as expected.

## Current Behavior

The `ufo ship` command gets stuck at the ECS service creation step, displaying the error message:

```bash
CREATE_IN_PROGRESS AWS::ECS::Service EcsService Eventual consistency check initiated
```

The error in AWS reads:

```plaintext
service demo-web-dev-EcsService-QY7NEm2trctk was unable to place a task because no container instance met all of its requirements. Reason: No Container Instances were found in your cluster. For more information, see the Troubleshooting section of the Amazon ECS Developer Guide.
```

## Step-by-step reproduction instructions

1. Install UFO:

```bash
gem install ufo
```

2. Set up AWS config and credentials:

```bash
# ~/.aws/config
[dev]
region = us-west-1
output = json

# ~/.aws/credentials
[dev]
aws_access_key_id=REPLACE_ME
aws_secret_access_key=REPLACE_ME
```

3. Set AWS\_PROFILE and verify credentials:

```bash
export AWS_PROFILE=dev
aws sts get-caller-identity
aws s3 ls
```

4. Create ECS cluster named `dev` in the `us-west-1` region:

```bash
aws ecs describe-clusters --clusters dev --region us-west-1 --profile dev
```

5. Set up the demo project:

```bash
mkdir demo && cd demo
aws ecr create-repository --repository-name demo
REPO=$(aws ecr describe-repositories --region us-west-1 --profile dev --repository-name demo | jq -r '.repositories[].repositoryUri')
echo $REPO
AWS_PROFILE=dev ufo init --app demo --repo $REPO
```

6. Ship the code:

```bash
AWS_PROFILE=dev ufo ship -y
```

7. Observe the error:

```bash
CREATE_IN_PROGRESS AWS::ECS::Service EcsService Eventual consistency check initiated
```

## Code Sample

## Solution Suggestion

Unsure. This prevented me from getting going with UFO.

Start with the `ufo ship -y` entry point and reproduce the deployment using the documented `dev` ECS cluster in `us-west-1`. Trace the ECS service creation and task-placement status behind the `CREATE_IN_PROGRESS` message; done means the reported deployment behavior is addressed when no container instance is available, with the documented reproduction completing or failing clearly.
