Resolve Customer Account question; add commercial subscription research

Record B2B SaaS subscriber tenancy and Stripe billing source notes. Resolve
the Customer Account open question: reject it as canonical, add Commercial
Record and Commercial Relationship to the Record and relationship layers, and
document Subscriber as a convenience term only.

## Conflict: Customer Account
Problem: `customer account` collapses login account, B2B subscriber organization,
Stripe billing customer, and CRM account into one product noun.
Source evidence:
- Auth0 uses Subscriber for tenant holder, not customer account (`b2b-saas-subscriber-tenancy.md`)
- Stytch: organization is the customer (`b2b-saas-subscriber-tenancy.md`)
- Stripe Customer is billing object with subscriptions, not login (`stripe-customer-billing.md`)
- ZITADEL/Keycloak org-as-tenant has no Customer Account type (`zitadel`, `keycloak` notes)
Canonical stance: **reject Customer Account** as canonical term. Resolve by layer:
- login/access → Account;
- subscribing company → Organization + Customer role + Tenant;
- billing/CRM → Commercial Record;
- vendor↔customer link → Commercial Relationship.
## Review Queue
- [ ] Decide Customer Account canonical concept — ZITADEL org-as-customer suggests
Organization + Tenant link, not separate Customer Account entity.
- [x] Customer Account — resolved; use Commercial Record + Commercial Relationship.
- [ ] Decide Realm specialization — Keycloak evidence supports Realm as Scope
specialization; promote in glossary if scenario review confirms.
- [ ] Split authz `member` relation from social Membership in downstream adapters.
