Launch HA Tenant

Opens the infrahive PR for a new tenant (runbook step 3) by running the Launch HA Tenant workflow. It also creates the tenant's client record in the Core database(s).

Lowercase letters, digits and hyphens, starting with a letter.

Environment

Use Both for a real launch so staging and production get the same client ID. A single environment writes only that side's client record.

The suggestion is the cluster with the fewest tenants; VM sizes differ, so check before accepting it.
