Update hub subdomain
Replaces the hub’s subdomain. Side effect: when the subdomain actually changes, all Stripe payment links for this hub are recreated — any external URLs holding the previous payment link will stop working. Use GET /hub/domain/availability to validate the new subdomain before calling this.

Check subdomain availabilityRead-only check — does NOT mutate the hub. Returns `available=false` with `reason=reserved` when the subdomain is on the reserved list, or `reason=taken` when another hub already uses it. This check does NOT exclude the caller's current hub — querying your own subdomain returns `reason=taken`.
