fix(pleno-vue): keep Fakturer nu visible on red-flagged customers (#279)

## Why

PR #271 made the `Fakturer nu` button visible again on multi-flag
customers in
the Kunder til gennemgang panel, but the button's v-if still gates on
`customer.requires_action`. On customers with manual (red) flags where
`requires_action` is false — e.g. flagged but the period's unbooked
transactions
are zero — the button stayed hidden in the right rail even though there
is
clearly something that needs the superuser's attention.

## What changed


`src/views/dashboards/superUserDashboard/InvoicingBillingPeriod/views/InvoicingBillingPeriodViewAll.vue`:

- New helper `hasRedFlags(customer)` next to `hasMultipleRedFlags`.
- Fakturer nu button v-if → `tmpFilters.displayRequiresAction &&
(customer.requires_action || hasRedFlags(customer))`.
- The `Gennemgå flag` tag remains gated on `hasMultipleRedFlags` (>= 2)
so the multi-flag warning is still loud.

`tests/unit/invoicing-period-queue-state.behavior.spec.js`:

- New test: `keeps the Fakturer nu button visible for customers with red
flags even when requires_action is false`.
- Sanity-checked: with the fix reverted, the test fails on the
visibility assertion; with the fix in place, it passes alongside the
existing 23 cases.

## Verification

| Check | Result |
|---|---|
| `npm run lint` | ✓ clean |
| `npm run format:tests:check` | ✓ clean |
| `npm run i18n:v2:check` | ✓ pass |
| `npm run test:unit:fast` | ✓ 1348/1348 (incl. new regression test) |
| `npm run build` | ✓ pass |

## Risk

- Surface-only v-if change. No API, data shape, or permission changes.
- Customers with red flags that previously showed neither the button nor
the
  `Gennemgå flag` tag now get the Fakturer nu button back. The button is
still scoped by the existing `v-if/v-else-if` chain (`all booked`, queue
blocked, draft blocked, action), so it does not appear where it
shouldn't.
