Create requires --region-id copied from docs or from elastic cloud serverless regions list-regions. A typo comes back as a raw 400.
On create (and hosted create-deployment if the body is a region error): append elastic cloud serverless regions list-regions (or the hosted equivalent). Do not preflight the region list in MVP.
Acceptance: create with --region-id not-a-region mentions list-regions on stderr. --json includes error.hint.
