Rebrand to Waseel, swap Stripe for Areeba, add phone-ready auth and DB seed

- Rename app: Waseel (name, slug, scheme waseel://, com.waseel.app ids, splash)
- Payments: replace Stripe with Areeba hosted checkout (create/verify API routes,
  lib/areeba.ts, WebBrowser-based payment flow)
- Maps: migrate address autocomplete to Places API (New), drop legacy library
- Web support: map stub for web (native maps are iOS/Android only)
- Auth: keep email + Google OAuth; fix OAuth redirect for Expo Go
- Add scripts/seed-db.mjs (schema + Lebanese driver seed)
- Pin Expo SDK 51 compatible package versions
