## Problem
Onboarding credit rewards (install apps, import contacts, invite team)
were silently dropped. They credit the workspace balance via
`billingCustomer.increment(...)`, but no `billingCustomer` row exists
until the plan step (it's created lazily when the first subscription is
set up, which is after those steps). So the increment affected 0 rows
and the credit was lost. A user installing 3 apps saw only the trial
grant, not the expected +1.5 credits.
## Fix
Create the Stripe customer + `billingCustomer` row eagerly at signup via
a new `BillingCreditService.ensureBillingCustomer`, called from
`signUpOnNewWorkspace` after the workspace transaction commits. It is
idempotent, guarded by `IS_BILLING_ENABLED`, and non-blocking (failures
are logged, not thrown). The later subscription flow reuses this
customer (no duplicate Stripe customer), and trial eligibility is
unchanged since the customer has no subscriptions yet.
