sanikakhupire/sahay-setu ? reverse-engineered prompt

Build me a web app called Sahay Setu for ward or RWA level emergency coordination during floods or local crises.

Residents should be able to sign up with their phone number, verify with OTP, and pre register emergency resources they can offer, like vehicles, medicines, food, water, or shelter. During an emergency, people should be able to post urgent needs and the app should match them with nearby available resources on a map, then help dispatch the closest volunteer in real time. I want a clean mobile friendly experience that also works like a PWA, with an interactive map for location based matching and live updates as requests get assigned or completed.

Please include roles for resident, volunteer, and admin, basic login security with JWT, and an admin area for managing users, resources, and requests. Use a modern simple UI, and if you need current docs for anything like maps or realtime features, look them up online.
