fix: resolve lint issues (XSS K601, knip unused exports, eslint errors)

- Fix XSS warnings in user.tsx by adding safe attribute to elements
- Remove unused exports: ChunkUploadRequest, getArchiveInfo,
  getFileForDirectDownload, createDirectDownloadHeaders, createConverterArchive
- Fix eslint no-unused-vars errors across multiple files
- Fix pdfmathtranslate async Promise executor issue
- Update tests to use toThrow instead of toMatch for Error objects
- Apply prettier formatting
