/**
 * End-to-end coverage for the Management section: add a Company, then a
 * Customer linked to that company (via the searchable combobox + rep
 * users dropdown + lat/lng inputs), then a Supplier. Verifies the new
 * field shapes (geoPoint + relations) round-trip through the live PB.
 *
 * Requires the same auth fixture as `auth.spec.ts` — a seeded
 * PocketBase user with E2E_TEST_EMAIL / E2E_TEST_PASSWORD. Without
 * that we skip the whole file rather than silently passing.
 *
 * Cleanup: each spec records the ids it created into a per-test
 * `cleanup` array and deletes them in afterEach. The auth user itself
 * is created by the existing test fixture (see e2e/_helpers.ts).
