Address review: playable PLAY/NEXT, visible rename editor, accurate copy

- PLAY and NEXT continue into the following scenes, so they stay
  enabled while any scene in the project has a shot, not only the
  selected one.
- Renaming a shot drops the number and ellipsis so the editor is no
  longer hidden; qa-scene-controls checks a long rename stays visible.
- PLAY, NEXT, EDIT DETAILS and SHARE SCENE tooltips describe what the
  buttons do, translated in every shipped language.
- The primary actions and the file row keep a hover state.
- Docs: the EXPORT rename in DIRECTOR-SHARING and the playback button
  states in CURRENT-STATE are accurate.
- Test the voice "authoring" alias through set_panel_open.
