* Implement atomic updates for gift card and reward point decrements, enhance error handling for insufficient balances, and add regression tests for concurrency safety. * Add translations for insufficient gift card balance and reward points error messages across all supported languages. * Reorder `clear_suspended_sale_detail` call to ensure transactional consistency. * Reorder `clear_all` call to align with success and error handling logic. * Ensure soft-deleted gift cards are excluded in balance updates. * Refactor change_quantity logic with atomic upserts, improve error handling for insufficient stock, and update related tests and constants. * Added check for NEW_ENTRY * Added unit tests to test changes. * Fix class name casing in ItemQuantityTest for consistency. * Fix Bulgarian translations for insufficient balance error messages in Sales module. * Fix Greek translations for insufficient balance error messages in Sales module. * Fix Armenian translations for insufficient balance error messages in Sales module. * Fix Tamil translations for insufficient balance error messages in Sales module. * Implement race condition testing for database methods with concurrent process support. * Fix class name casing in ItemTest for consistency. * Improve concurrent process handling in race condition tests; add readiness and synchronization barriers. * Improve handling of process I/O streams and timeout management in race condition tests. * Add test for decrementing gift card value when marked as deleted * Add `finally` block to ensure proper cleanup in async database race condition tests * Improve error handling and timeout management in async database race condition tests. * Refactor test utilities to use shared `EmployeeFixtureTrait` and `ItemFixtureTrait`. * Track process exit codes explicitly in race condition tests for improved error detection and debugging. * Improve error handling in `ConcurrentDbRaceTrait` by adding exceptions for `mysqli_poll` and `mysqli_reap_async_query`.

* its write in a single atomic upsert, so that two concurrent sales of the

* same item/location can never both read the same stale quantity and
