- Validate paymentType is a non-empty string before processing
- Reject negative or zero amounts for all payment types
- Enforce full payment coverage before completing a sale
- Bypass coverage check for invoice and quote mode sales
- Require a valid gift card number before decrementing value;
rollback and return insufficient balance error on missing input
- Add "amount_due_not_covered" and "negative_amount_invalid"
translations across 40+ locales
- Add test coverage for gift card validation, negative amounts,
and quote/invoice zero-payment completion
- Rename snake_case locals to camelCase in postComplete (no behavior change)

* 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
