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.
- config_form.yaml preview block (optional headerPartial), reported in the form schema as preview
- fields with context: preview show only on the preview screen and are never written
- form messages preview and edit; recordActions without a preview block stops boot
- SPA route {id}/preview, PreviewView and PreviewField, record actions in the footer
- mapWinterUrl maps preview/:id; the update form returns to the preview
- summer-callout partial style classes for status hints
- README, docs, OpenAPI document, TS types and the embedded build updated
