TF Clone FastAPI repo and prep to deploy to ECR

[wesdottoday]

• [ ] Terraform should clone the FastAPI repo
• [ ] Build the container
• [ ] Push container to ECR in the appropriate region
• [ ] Store ECR URI as a variable in TF

Not sure what the underlying process will look like here, but we should be able to clone a repo, build a container, and push to a repository for AppRunner to pick up eventually.
