fix(ci): separate short-lived CI VPC + fix 8 module lifecycle failures

Two architectural changes:
1. Created terraform/ci-vpc/ — a short-lived VPC for L1 module lifecycle
   testing, separate from the long-lived platform VPC. Created before
   VPC-dependent modules (alb, ecs-service, rds, uptime) are tested,
   destroyed after. Outputs (vpc_id, subnet_ids, sg_id, cluster_arn) are
   passed to those modules via scripts/run_lifecycle_test.sh +
   run_lifecycle_destroy.sh wrappers that inject the CI VPC outputs into
   the example contracts.
2. Updated the workflow to use ci-vpc-apply → lifecycle (with artifact
   passing) → ci-vpc-destroy (always runs).

8 module-specific fixes:
- s3: unique bucket names (acdl-ci-s3a-simple/complex) instead of
  globally-taken 'my-simple-bucket'
- kms-key: alias name with no spaces (locals.tf → alias/acdl-ci-kms)
- iam-role: example contract uses role_name (not name, which the interface
  doesn't declare)
- ecs-service: example contract uses family (not name); VPC inputs
  (cluster_arn, subnets, security_group) injected by CI VPC wrapper
- uptime: added subnets, security_group, cluster_arn to interface + module;
  network_configuration is dynamic (only when subnets provided)
- rds: added subnet_ids input + db_subnet_group resource (conditional
  on subnet_ids being non-empty)
- alb: removed hardcoded placeholder sg/subnet values from examples;
  vpc_id + subnets + security_group injected by CI VPC wrapper
- cloudfront: removed invalid placeholder WAF ARN from complex example

Regression: 479 passed, 0 skipped, 5 deselected. All 24 example contracts
pass --check-only.
