Re-opening a Concept wizard now lets the user preview/download what they already
uploaded (PRD 0001 goal 2).
- document-chip: optional previewUrl input → a "Voorbeeld / Download" link (opens
the stored bytes; server serves inline for pdf/image, attachment otherwise).
- previewUrlFor callback threaded document-upload → document-category → single-upload
(which builds the URL from a completed upload's documentId). Keeps URL-building out
of the presentational atoms.
- registratie + herregistratie wizards supply previewUrlFor via UploadAdapter.contentUrl,
returning undefined for dev-simulation `demo-*` ids (no stored bytes → no link).
- Story: DocumentChip/WithPreview.
Gates green: vitest 128, lint, ng build, check:tokens; backend dotnet 56.
(build-storybook has a pre-existing Compodoc/$localize issue in untouched files.)
