feat(page-layouts): a maker can lay out a case page per case type

[rubenvdlinde]

Change case-page-layout-per-case-type (not archived: two tasks are owed by sibling repos). A maker can now author a page layout per case type in the detail-page editor: the tabs and their kinds and order, a widget grid with four widths, display conditions and a high-contrast mark per widget, the header fields, the task-list columns and search fields, and the document upload fields with their visibility and default. The layout is saved as a pageLayout object and served by the buildiq-page-layout leaf.

What this PR adds on top of what development already has (schema, leaf, applies-to panel):

• PageLayoutBodyEditor.vue inside AppliesToPanel.vue (tasks 6.1 to 6.6). Tabs are reordered with Up and Down buttons instead of dragging, so a keyboard and a screen reader can do it (WCAG 2.5.7); the design is corrected in tasks.md. Save stays disabled while a hidden upload field has no default; the server refuses it as well.
• A save warns when a leaf tab names a leaf id no installed app offers (task 2.2): PageLayoutAuthoringService::save() now reads the ids from OpenRegister's IntegrationRegistry::listIds() and stays silent when the registry is absent.
• Three seed layouts for dossiq/case in the demo dataset (schema-wide, bouwvergunning, evenementenvergunning), each validated against the pageLayout fragment.
• English and Dutch strings, docs/elements/case-type-layouts.md, and tests/e2e/page-layout-editor.spec.ts (API level).

Rows: form-layout-per-type and form-screen-override stay building. Their remaining half is a nextcloud-vue change (runtime-detail-layout: CnDetailPage merges the leaf's answer over its manifest config, task 3.2) and a hand-off to dossiq for its task list and upload dialog (task 8.5). Both are drafted for Ruben, not filed.

Also in this PR, from the hermiq lane: ai-in-app-assistant and ai-record-summary are set built with a reference to hermiq's archived change 2026-10-01-agents-bound-to-their-app (hermiq development d3cac1131), after reading hermiq's development.

Tests (written by the previous lane; green on this head):

• 2.2: PHPUnit PageLayoutAuthoringServiceTest::testASaveWarnsOnALeafTheRegistryDoesNotKnow.
• 6.1 to 6.6: Vitest tests/components/PageLayoutBodyEditor.spec.js, tests/components/AppliesToPanel.spec.js.

Inherited, not fixed here: the vendored hydra-gates in composer check:strict fail gate-101 on the five buildiq schemas that carry reasoned no-demo skips since #853; CI's required gate run (hydra-gates@main) honours the reasons.

Live check: open an app's detail-page editor, Applies to: schema case, type property caseType, value bouwvergunning; add a widget tab with two widgets of width Small and Large, add a condition status is not empty, add an upload field confidentiality hidden with default intern, save as Published. GET /apps/buildiq/api/page-layouts lists it; the leaf buildiq-page-layout for a bouwvergunning case returns the tabs in order.

Verification on this head (base development f05abe1, which the branch contains): composer check:strict: lint, phpcs, phpmd, psalm, phpstan green, PHPUnit OK (1329 tests); its vendored gates fail gate-101 (inherited, above) and gate-16 on seven untagged editor helpers, which the last commit tags. CI's gate run (hydra-gates@main, full scope, --require-full-coverage) on the final head: all 85 applicable gates passed, exit 0. npm lint 0 (warnings only), stylelint 0, format 0, vitest 0 (1700 tests), test:l10n 0, check:l10n-js 0, check:schema-l10n 0, check:manifest 0, check:gitignore 0, check:nc-floor 0. parity_verify --strict: census only. No local production build; CI's Frontend Build answers that.
