TiagoDezan/gestion_semilla ? reverse-engineered prompt

Build me a web app for a church management system called Semilla de Vida.

I want it to help with member management and treasury, so people can register members with personal, family, and church info, search and filter them, edit profiles, and generate printable PDF reports or member sheets. For the finance side, I need a dashboard that shows income, expenses, and current balance, plus a way to record offerings, tithes, expenses, and other movements, with categories and accounts, a calendar view, and monthly, quarterly, and yearly reports in PDF.

It should have secure login with different roles like admin, treasurer, and secretary, support Portuguese and Spanish, work well on mobile and desktop, and include dark mode and a few theme color options. Use the existing backend setup if there is one, and look up current docs online if you need to.
