MelissaPlano/AlterarPlano desktop: cards min-h 300 + body scroll

Aplica o mesmo fix do MelissaPerfil/Negocio:
- align-items: start no grid (cells nao stretch p/ row height)
- Cards min-height 300px + max-height 100% (do container)
- .mpl-w__body / .map-w__body com flex: 1 + min-height: 0 +
  overflow-y: auto (scrollbar fina)

MelissaPlano: vale pros 2 cards do main (Recursos / Historico) e
pros 2 cards da sidebar (Plano atual / Resumo) — quando o user
tem features longas ou muitos eventos, scroll interno engata.

MelissaAlterarPlano: aplicado SO na sidebar (Plano atual / Filtros).
Os plan cards do main (.map-plan) ficam fora — sao product cards
com layout proprio (preco grande + 3 CTAs).
