fix(i18n): the video menu's download row says "Download…", and counted copy is pluralized

- The row opens the download dialog, so it is labelled so; the download's state ("Downloaded",
  "In queue") is its hint, not its label.
- The share dialog's expiry ("1 days") and a link's view count ("1 views") go through i18next's
  plural forms (`count`).
