Pamoja setup guides

Step-by-step, click-by-click setup for the core group journey: the dashboard, the President assistant, members and roles, dues and who has paid, the treasury and payments, meetings and hosting, the live njangi draw and rotation, loans and welfare funds, channels that replace WhatsApp, and the group's bylaws. In English and French. Each guide is real screenshots captured from the live app, so they never go stale.
