feat: add studentRevenueParser middleware to handle city and region filter logic

src/libs/middlewares/studentRevenueParser.js

+/*
+Middleware que remove o campo "region" quando o campo "city" está ativo nos filtros.
+Devido à limitações na tabela de dados, quando ambos campos estão ativos o filtro por
+"região" funciona incorretamente. 
+*/
