feat: enhance AbacatePay donation system with updated docs and form fields

Updated ABACATEPAY_SETUP.md with comprehensive setup guide, including environment variables, API key instructions, webhook configuration, donation flow, and field details for better integration clarity. Added required fields (phone, CPF/CNPJ) to the donation form in app/[locale]/apoiar/page.tsx to collect essential donor information and improve compliance. This ensures smoother setup and more robust donation processing.
