Replace Aspose.Words with OnlyOffice Document Server for generating bitmap previews of office documents (Word, Excel, PowerPoint, etc.). Backend: - Add cista/onlyoffice.py conversion client - Convert office docs directly to PNG via OnlyOffice, then AVIF via pyvips - Make office previews optional based on OnlyOffice availability - Remove Aspose.Words dependency and all related code - Add spreadsheet and presentation format support Frontend: - Mark office files as previewable in Document.ts - Add office extensions to MediaPreview.vue preview list - Fix pre-existing @ts-ignore in HeaderMain.vue Tests: - Fix test_lrucache.py parameter name (open -> opener) Also run ruff format across the codebase to satisfy linter checks.
