supdados/projetosRj ? reverse-engineered prompt

Build me a web app for managing public sector projects for the State of Rio de Janeiro, with login through Gov.br.

I want it to help teams track projects in a simple flow like Project, Stage, and Task, with people assigned to work items, comments, attachments, a Kanban style board, dashboards, global search, and a calendar view. It should feel like an internal tool for government staff, clean and practical, with forms, tables, and pages that make it easy to follow what is happening on each project.

Use Python on the backend with Flask, database migrations, and a MySQL setup, and make sure the app is secure with CSRF protection and basic rate limiting. The current production version seems to use server rendered pages, so build it that way unless you need to keep things modular for a future SPA. Include the environment config, login flow, and a working local setup. If you need current docs for Gov.br or Google Calendar, look them up online first.
