Initial commit: dating app web frontend (Next.js)

Phone+OTP auth, staged onboarding, admin-approval-gated home screen,
and the full discovery/match/chat UI (swipe deck with drag gestures,
match modal, profile detail, filters, messages/chat) wired to the
real backend, styled after a Figma dating-app UI kit.
