BillingAccount

Billing Account represents the payment entity that owns one or more organizations. Tier limits and quotas are enforced at the billing account level, not per-organization.

This prevents abuse where users could create multiple orgs to multiply their quotas. For example:

• Business tier ($29) = 10k links/month across ALL orgs in the billing account
• Not 10k per org (which would be 30k for 3 orgs)
