In standalone mode (no DATABASE_URL), the in-memory user store only had
hardcoded demo accounts. Any real email the developer used was lost on every
server restart, causing OTP requests to silently fail with "unknown email".
NewUserRepository now accepts devEmail + devPassword. If DEV_USER_EMAIL is
set, that account is seeded on every startup alongside the demo users. The
developer's email is always registered, OTPs route to notify (or log to
console), and re-renders/restarts no longer break the auth flow.
New config fields: DevUserEmail (DEV_USER_EMAIL) / DevUserPassword
(DEV_USER_PASSWORD, default: "DevPassword1").
