apply-onboarding-pipeline.ts and migrate-onboarding-templates.ts resolved the
engine as `DATABASE_URL ?? ''`, diverging from server.ts's production
fallback. On the prod box (DATABASE_URL unset) each script opened a brand-new
empty SQLite file, "succeeded" against it, and Postgres was never touched.
resolveDbUrl()/requireDbUrlForEnv()/pgTargetDescription() now live in
db-pg.ts as the one place this is decided; server.ts and both scripts call
it. The scripts additionally hard-fail (never fall back to SQLite) when
NODE_ENV=production resolves nothing, log their target engine before doing
any work, and close the DB handle in a finally.
Also lands client_module.created_at (nullable, additive) — schema groundwork
FIX D uses to measure a no-tick project's age from its real creation date
instead of treating a missing done_on as infinitely old.
