Use team-prefixed names for ECR and ECS in CI workflows (#96)

## Summary
docker-build and ecs-deploy workflows used the bare repo name for ECR
repos and ECS services. With team-prefixed naming, they need
`{team}-{repo_name}`.

Both get the team from the CI broker output (already resolved via GitHub
API).

## Test plan
- [ ] Merge, retrigger test app CI — docker build should push to
`testteam-platform-test-app` ECR repo
