docs(quick-261007-qgx): record heading from translatable fields

The record heading, breadcrumb crumb and document title took the first
plain text field only, so records named by an mltext field fell back to
the generic update message. A shared recordDisplayName helper now takes
the first text or ML field and reads its default locale, then the first
non-empty one.

+# Quick 261007-qgx: admin record heading uses translatable (mltext) fields
+
+The admin record heading, breadcrumb record crumb and document title read the
+first `text` field only, so records whose name field is `mltext` (journal Post
+title, Category name) fall back to "Edit record".
+
+## Task 1: shared recordDisplayName helper
+
+- files: admin/src/components/form/formState.ts, admin/src/views/FormView.vue, admin/src/views/PreviewView.vue
+- action: add `recordDisplayName(fields, values, enabledLocales)`: first field
+  of type `text` or an ML type (`isMLFieldType`) in schema order; plain values
+  as today (string/number, trimmed); ML values use the default (first enabled)
+  locale, else the first non-empty locale, else ''. Both views use it with
+  `schemaEnabledLocales(schema.meta)`.
+- done: plain `text` behaviour unchanged; an mltext first field names the record.
+
+## Task 2: tests
+
+- files: admin/tests/form/formState.test.ts, admin/tests/form/FormView.test.ts, admin/tests/form/PreviewView.test.ts
+- action: helper cases (plain, default locale filled, default empty + other
+  filled, all empty, non-text first field skipped); FormView and PreviewView
+  show the default-locale value as heading and record crumb for an mltext field.
+- verify: `npm test`, `vue-tsc --noEmit`.
+
+## Task 3: ship
+
+- rebuild the embedded admin shell (`npm run build` → modules/boardwalk/dist),
+  `go vet ./... && go test ./...`, tag and push v0.1.12.

+# Quick 261007-qgx: admin record heading uses translatable (mltext) fields
+
+- `recordDisplayName(fields, values, enabledLocales)` in
+  `admin/src/components/form/formState.ts`: the first `text` or ML field in
+  schema order names the record; an ML value reads the default (first enabled)
+  locale, then the first non-empty locale, else '' (the generic message stays).
+- FormView and PreviewView both use it with `schemaEnabledLocales(schema.meta)`;
+  plain `text` behaviour is unchanged.
+- Tests: five helper cases in `formState.test.ts`; FormView and PreviewView
+  cases for an mltext first field (heading and record crumb). Both view tests
+  fail without the fix. Admin suite 1090/1090, `go vet` and `go test ./...` green.
+- Embedded admin shell rebuilt (`modules/boardwalk/dist`), shipped as v0.1.12.
