Add self-hosted auth, admin API, and owner web dashboard

- Replace Clerk with self-hosted JWT auth (register/login/verify, bcrypt
  passwords, Gmail OTP with console fallback)
- Add lib/db.ts pg pool + transaction helpers; seed script migrates legacy
  Clerk-era schema (drop clerk_id, enforce UUID ids and unique email)
- Add owner-gated admin API: stats, users, drivers CRUD, rides
- Add dashboard/ Vite React owner dashboard (login, overview, users,
  fleet, rides) with dev-server proxy to avoid Expo CORS middleware
- Add scripts/set-owner.mjs for role management
