fix: melhora UX de softwares e campos personalizados

Softwares instalados:
- Corrige contador de paginação (mostra 1-30, 31-60, etc.)
- Remove tooltip do botão de limpar pesquisa

Campos personalizados:
- Adiciona mensagem indicando tipo de dispositivo (desktop/celular)
- Melhora mensagem quando não há campos disponíveis
- Adiciona botão X para limpar valor de campos texto/número
