2.0: dictado de platos/ingredientes + calendario más alto en iPad/Mac

- Dictado por voz (Speech/SFSpeechRecognizer, on-device) en el nombre de
  plato y en ingredientes, con transcripción en vivo.
- Un solo texto dictado se separa en ingredientes individuales vía Apple
  Foundation Models on-device (IngredientParser), con fallback heurístico.
- Permisos de micrófono y reconocimiento de voz en Info.plist.
- Cadenas de dictado en los 6 idiomas.
- iPad/Mac: el calendario reclama ~50% de la altura disponible en lugar
  de quedar fijo a ~240px; iPhone (compact) sin cambios.
