Fix ModuleNotFoundError: No module named 'pkg_resources'

[Copilot]

pysolr imports from pkg_resources (part of setuptools), which is no longer bundled by default in newer Python environments, causing a startup crash when Django loads search.urls.

O que esse PR faz?

Adiciona setuptools>=78.1.1 explicitamente ao requirements/base.txt, garantindo que pkg_resources esteja disponível. A versão mínima 78.1.1 também evita uma vulnerabilidade de path traversal em PackageIndex.download presente em versões anteriores.

Onde a revisão poderia começar?

requirements/base.txt — única linha adicionada.

Como este poderia ser testado manualmente?

1. Construir a imagem Docker sem setuptools instalado previamente
2. Iniciar a aplicação e verificar que GET /search/ não retorna erro 500 com ModuleNotFoundError: No module named 'pkg_resources'

Algum cenário de contexto que queira dar?

No Python 3.11+, setuptools (e consequentemente pkg_resources) não é mais instalado automaticamente no ambiente. O pysolr==3.9.0 faz from pkg_resources import ... no nível de módulo, o que quebrava o carregamento de todas as URLs da aplicação ao importar search.urls.
