fix(db): run wait-for-db inline in migrate/seed/reset (pnpm skips pre-* hooks)

pnpm 9 does not auto-run npm pre-* lifecycle scripts (enable-pre-post-scripts
defaults to false), so the pre-migrate/pre-seed/pre-reset hooks added in the
prior commit never executed under the Dockerfile entrypoint
`pnpm --filter @groombook/db migrate`. Chain wait-for-db.mjs directly into the
migrate/seed/reset scripts so the DNS pre-resolve actually runs on the real
invocation path. Verified locally that `pnpm --filter @groombook/db migrate`
now runs wait-for-db before drizzle-kit. (GRO-2163)
