/**
 * Migration: add v5 quote fields to the `quotes` collection.
 *
 * Idempotent — running twice is safe. Each step checks whether the
 * field already exists (by `name`) before adding it; for the `status`
 * select field, it merges "template" into the existing values array
 * without disturbing the rest.
 *
 * Required env (in .env or shell):
 *   NEXT_PUBLIC_POCKETBASE_URL
 *   PB_ADMIN_EMAIL
 *   PB_ADMIN_PASSWORD
 *
 * Usage:  npx tsx scripts/migrations/2026-06-23-add-quote-template-fields.ts
