[RoxyRoses]

Pull Request: Atualização da Página de Novo Guardião para Consistência com o Design System

Resumo

Este pull request atualiza a NewGuardianPage para usar os componentes de botão do Design System, garantindo consistência visual e alinhamento com práticas modernas do Flutter.

---

Alterações Realizadas

1. Substituição de Widgets Depreciados:

   • Substituído o RaisedButton pelo PenhasButton.roundedFilled para o botão de ação "Adicionar guardião".
   • Substituído o FlatButton pelo PenhasButton.text para os botões de ação em diálogos.

2. Compatibilidade com Null Safety:

   • Removido o operador de acesso condicional (?.) desnecessário em chamadas do WidgetsBinding.

3. Simplificação de Código:

   • Removidas propriedades redundantes (elevation, color, shape) no antigo botão, agora gerenciadas pelo Design System.
