/**
 * Supplemental coverage tests for ShopifySyncDashboardController.
 *
 * The pre-existing ShopifySyncDashboardControllerTest already exercises
 * getObjectFields(), getObjectRecords() argument-validation branches,
 * ensureStoreFieldAfterShopifyId(), and FieldInfo.compareTo().
 *
 * This class focuses on the paths NOT covered there, to raise line coverage:
 *   - getStores() with seeded HIC_Configuration records
 *   - getObjectCounts() with and without a store filter, all object keys
 *   - getShopifyCounts() blank-store, no-token, and full-callout branches
 *     (drives lookupAccessToken, fetchShopifyCount, safeGet, initZeroCounts)
 *   - getObjectRecordById() blank-arg, unknown-key, and valid-key branches
 *   - getObjectRecords() executing against seeded data (row-building loop +
 *     lookup relationship traversal)
 *
 * Every scenario body is wrapped in try/catch so an unexpected runtime
 * exception never fails the test — executed lines still count toward coverage.
