- Configura base URL da API através de variável de ambiente (.env.example).
- Cria instância do Axios para comunicação com a API e gerenciamento de token de autenticação.
- Adiciona lógica de submissão do formulário de login, incluindo chamadas à API.
- Gerencia estados de carregamento e exibe mensagens de erro/sucesso.
- Integra react-hot-toast para notificações de sistema.
- Redireciona a rota raiz (/) para a página de login.
