Fix video action button wrapping + bundle textbook seed JSONs

- VideoActionsView: stack icon over title via a custom label style so
  the Stream/Download/Play row fits iPhone width without wrapping
  mid-word ("Stre am", "Down load").
- project.yml: add textbook_data.json and textbook_vocab.json to the
  Conjuga target's Copy Bundle Resources. They were missing, so
  DataLoader.seedTextbookData early-returned every launch and the
  textbook never appeared in the Book tab. Regenerated Conjuga.xcodeproj.
