2.0: banner export descartable + slider calendario/platos en iPad

- El banner "Your week is ready to export" ahora tiene botón de cerrar (X)
  que lo oculta para esa semana (persistido en AppStorage).
- iPad/Mac: handle arrastrable entre calendario y platos para rebalancear
  el alto (fracción persistida, clamp 0.28–0.72); el calendario y la lista
  se recalculan al arrastrar. Sustituye la altura fija anterior.
