// One-off deploy step for the Client Detail redesign: writes the live onboarding-template
// settings with the composed quotation-led pipeline (shared front + per-module tail), then runs
// the tick-preserving migration so existing SMS/RTGS/MobileApp projects adopt the new steps.
// Idempotent ONLY as long as the templates below haven't been owner-edited since: each setting
// is written only if it is still ABSENT, so a plain re-run never clobbers an owner's edit made
// in the Modules onboarding-template editor. Pass --force to unconditionally overwrite every
// template with the settings below — this DOES clobber owner edits, use with care.
// Run from repo root, naming the database explicitly (this header previously omitted the
// DATABASE_URL prefix — followed literally on the production host it resolves to SQLite, not
// the real database, and the script now refuses rather than migrating the wrong DB):
//   DATABASE_URL=postgres://… npx tsx apps/hq/scripts/apply-onboarding-pipeline.ts [--force]
// To deliberately run against a local SQLite database instead, opt in explicitly:
//   HQ_DB_TARGET=sqlite npx tsx apps/hq/scripts/apply-onboarding-pipeline.ts   (or --sqlite)
