v0.98.1

Fixed

• Papra DMS documents could not be previewed or opened, and showed 0 KB — Papra's file endpoint always serves application/octet-stream (an intentional XSS defence), so the in-app viewer rejected every linked document with a 415 "Preview not supported" error even though it downloaded fine. Linking now captures the document's real MIME type and size from Papra's metadata, and the preview/download handlers fall back to the stored MIME type when the DMS returns a generic octet-stream, so PDFs and text files render inline again. The "Open in DMS" link was also pointing at a non-existent path (/documents/<org>/<id>) and 404'd; it now uses Papra's real document route (/organizations/<org>/documents/<id>). Existing links keep their old metadata — re-link to pick up the correct size, MIME type, and URL (#451).
