## Problem
POST /master/api/order/items still returns
> Product 24: Reason comment is required for this product
for products in {21, 22, 24, 25, 26, 27}, even after #296 landed the
mobile POS step 2 note prompt.
The previous `buildAuditedOrderItemReasonPayload` only fell back through
`reason.reason_comment → reason.comment → notes → ''`. Any code path
that
calls `createOrderItem` without populating `notes` (copy-last-wash,
future callers, or even a user who clears the prompt) sent
`reason_comment: ""` and the backend correctly rejected it.
## Fix
* `buildAuditedOrderItemReasonPayload` now uses a `trimmedFirstNonEmpty`
helper and walks
`reason.reason_comment → reason.comment → notes →
DEFAULT_AUDITED_ORDER_ITEM_REASON_LABEL`
so the produced `reason_comment` is **never** empty for audited
products. `reason_code` and `reason_label_snapshot` keep the same
fallback semantics.
* `createCopiedOrderItem` in `POSDepartmentProcess.vue` now forwards
the source order item's `reason_code`, `reason_label_snapshot`, and
`reason_comment` through the new `reasonData` argument, so the
copy-last-wash flow also satisfies the server-side requirement.
## Tests
`tests/unit/orders-items.spec.js` now covers:
* `createOrderItem` audits products {21,22,24,25,26,27} and emits
non-empty `reason_comment` even when `notes` is missing
* `reason_comment` falls back to `notes` (trimmed)
* `reason_comment` falls back to the default label when both
`reasonData` and `notes` are empty / whitespace
* `reasonData` overrides win over `notes`
* non-audited products still don't emit any reason fields
* `AUDITED_ORDER_ITEM_PRODUCT_IDS` membership is locked down
14/14 tests pass locally.
## Production evidence
* Production bundle `Addons-*.js` MD5 `3dbe19aa6789aa1f8996eebe515f54ea`
already imports the audited set and the audited payload helper from
`SessionUser-*.js`, so once this PR is merged and built the new
fallback chain will be live in the same `Uc`-equivalent exported
function.
