- .docx now renders client-side via docx-preview (fetches bytes from our
own storage; works with private MinIO/disk). Drops Microsoft's hosted
Office viewer which can't reach a private object store.
- add office (.docx/.doc/.xlsx/.xls) + text/csv to PREVIEWABLE_MIMES so
/api/v1/files/[id]/preview returns a URL instead of rejecting them
(was surfacing as a misleading "Failed to load preview")
- legacy .doc + spreadsheets fall through to a download CTA (can't render
client-side); text/csv use the existing TextPreview
