Subject: [PATCH] Add seahaven-account-baseline deploy role; codify cfn-exec
 cloudfront/ssm (audit H-16)

- New githubdeploy-seahaven-account-baseline OIDC role (CDK pattern: assumes
  cdk-hnb659fds-*, scoped to the repo's main branch). Wires CD for the shared
  account-baseline repo (CloudTrail C-1 + AWS Backup C-7).
- Codify cloudfront:* and ssm:* on github-cfn-execution-role to reconcile
  out-of-band drift (audit H-16). These are needed by live SAM deploys
  (meal-order CloudFront; afterhours/payments/meal-order SSM params).

Deployed via change set wire-account-baseline-and-h16; stack now IN_SYNC.
IAM cross-review completed (new role confirmed; cfn-exec breadth documented).
