Root cause: drizzle-orm's HWM-based migrate() marked migrations as applied in the ledger but rolled back schema changes when it detected a dirty state. Replacing with execSync("pnpm exec drizzle-kit migrate") matches the K8s migrate-schema Job, ensuring reset leaves a fully-migrated schema before seeding. Fixes reset-demo-data CronJob failures and resolves seed-test-data relation-does-not-exist reconcile loop.

drizzle-orm's migrate() has a high-water-mark (HWM) bug: on a fresh DB,
migration 0000 sets the watermark to 2026-03-17. Migrations 0001, 0003,
0010, 0011 have stale 2025-era `when` timestamps and are silently
skipped. Migration 0003 (recurring_series) is the blocker — its skip
leaves `recurring_series`, `appointments.series_id`, and
`appointments.series_index` missing. A downstream migration inside
migrate()'s single Postgres transaction then fails, rolling back
everything including 0000's `staff` and `services` tables.
Replace the drizzle-orm migrate() call with `pnpm exec drizzle-kit
migrate` (hash-based). drizzle-kit applies every unhashed migration
regardless of `when` ordering, matching the K8s migrate Job exactly.
