- 005-create-billing-tables.sql: replace all `it0_shared.tenants` with
`public.tenants` and all `tenant_id VARCHAR(20)` with `tenant_id UUID`
to match the actual server DB schema (public schema, UUID primary key)
- packages/shared/testing src/test-utils.ts: add new quota fields
(maxServers, maxUsers, maxStandingOrders, maxAgentTokensPerMonth) to
TEST_TENANT mock to satisfy the extended TenantInfo interface, fixing
the @it0/testing TypeScript build error
