feat(wiki): drag-over visual, optimistic UI, and progress bar for raw material uploads

- Drag-over highlight (orange border + shadow + arrow icon) on the upload
  zone, using dragCounter to prevent flicker over nested children
- Optimistic list items appear immediately on drop/select with UPLOADING
  badge and progress bar, before the HTTP request completes
- Wire axios onUploadProgress through api.uploadRaw → store.uploadRawFile
  so the progress bar tracks real byte transfer (0–100%), with an
  indeterminate shimmer until the first tick
- try/catch around every upload: on failure, placeholder flips to an error
  state with ElMessage.error toast and a × dismiss button
- Upload all dropped/selected files concurrently via Promise.all
- i18n keys added (zh-CN + en-US): dropToUpload, uploading, uploadFailed,
  status.uploading, progress.uploading
