PR #308 (AUT-11) added a new e2e test for the XL Vask flag to Selvvask
navigation, but it failed the playwright-full-slice-ownership check
because it wasn't in any of the role-scoped ownedFilesByRole lists.
Since the Selvvash view is superuser-only functionality, this test
should be in the superuser role.
Adds a desktop-only Playwright @smoke test proving that clicking the
xlvask_usage_log token in an xlvask_missing_order_link flag row opens
a popup targeting the Selvvash (self_wash) view with the referenced
usage log ID (55) for the 2026-07-01..2026-07-31 period.
