Melhorias de usabilidade e aparência no ListView

Adicionadas funcionalidades de manipulação de eventos de clique do mouse
(`PreviewMouseLeftButtonDown` e `PreviewMouseRightButtonDown`) e suporte
para copiar informações do `ListView` com atalhos de teclado (`Ctrl+C`) e
menu de contexto ("Copiar coluna"). Implementado com `InputBindings`,
`CommandBindings` e `ContextMenu`.

Alterada a exibição das colunas do `GridView` para usar `TextBox` somente
leitura, permitindo seleção de texto, com customizações visuais como
cor de texto (`Foreground="#FF042271"`), fundo transparente e sem bordas.

Adicionado estilo personalizado para itens do `ListView`, incluindo
captura de eventos de tecla pressionada (`KeyDown`) e remoção do evento
de clique duplo do mouse (`MouseDoubleClick`).

Atualizadas colunas adicionais (`Unidade`, `Instalação`, `CNPJ`, `Razão
Social`) para seguir o mesmo padrão de somente leitura e aparência.

Essas mudanças melhoram a experiência do usuário, tornando a interface
mais prática e visualmente consistente.
