fix(l10n): the Page layout title rendered English to a Dutch user

[rubenvdlinde]

Fixes gate-101 manifest-l10n-coverage, failing on development.

What is wrong

The PageLayout page title has no key in l10n/nl.json, so a Dutch user sees the English source:

FAIL no nl.json key: Page layout

It titles the widget-grid layout designer (/pages/:id/layout, component PageLayoutDesigner).

Why nothing else caught it

From the gate's own message: check:l10n-js compares nl.json to nl.js, and a string absent from both is in sync. Only this gate looks at what the manifest actually renders.

The translation

Page layout → Pagina-indeling — the idiomatic Dutch for a page-layout designer.

There is no fleet compound to match: I checked opencatalogi, dossiq, openregister, thematiq and stackiq (none carry the key) and launchpad, which translates the bare Layout as Lay-out. Flagging the choice rather than burying it, in case the fleet would rather standardise on Paginalay-out.

Both catalogues

nl.js is updated alongside nl.json — adding to nl.json alone would simply trade this gate for check:l10n-js. This app's nl.js uses a different style from launchpad's (4-space, "key": "value"), and the patch follows the local one.

Verification

• check_manifest_l10n_coverage.py against this tree: no FAIL lines, checked 85 manifest string(s). Before the change it named Page layout exactly, matching CI's count of 1.
• nl.js evaluated as real JavaScript (stubbing OC.L10N.register) to confirm it still parses and that the new key's value is identical in both catalogues.

Why it reached development

Every Code Quality run on development was being cancelled rather than completed, so nothing reported it — see ConductionNL/.github#597 and the follow-up measurement in ConductionNL/.github#625.
