sabryio/whatsapp-campaigns-old ? reverse-engineered prompt

Build me a contact management app with WhatsApp campaign sending, like a small admin dashboard for teams that need to import leads, verify who actually has WhatsApp, and send scheduled message campaigns.

I want users to be able to sign up and log in, manage contacts with tags, bulk actions, and CSV export, then import contacts from CSV or XLSX with a friendly mapping and duplicate handling flow. There should be a way to connect multiple WhatsApp accounts, show QR codes for pairing, track connection status, and disconnect sessions later.

For campaigns, make a step by step builder where I can pick details, choose contacts, write messages, attach images from upload or a URL, then review and start, pause, or resume sending. I also want live progress while verification and sending are running, plus a history page, dashboard stats, audit logs, and basic settings for things like anti ban behavior and notifications.

Use the current docs online if you need to, and keep it polished for a real product.
