ramadhan sjamsani d9869bf6af Phase 3.4: customer OTP screen rewrite + lockout UX + bug fixes
OTP screen rewrite: 6 rounded boxes, auto-advance focus, auto-submit on the
6th digit, hardware-backspace on empty boxes (intercepted via Focus.onKeyEvent
since TextField.onChanged doesn't fire on already-empty input), resend
cooldown sourced from /api/shared/config/otp, and an inline error message
under the boxes instead of a SnackBar.

Several bugs fixed inline that surfaced during testing:

- ref.listen inside build() accumulates listeners on every rebuild — the
  resend countdown's per-second setState was piling up duplicate listeners
  so one error triggered N callback fires. Moved to ref.listenManual in
  initState; subscription disposed in dispose().

- RouterNotifier was calling notifyListeners() on every auth state change
  including AsyncError, which rebuilt the Navigator/Scaffold mid-snackbar
  and visually duplicated the error toast. Now skips AsyncError and
  same-data-variant transitions.

- ScaffoldMessenger.showSnackBar from a Riverpod listener callback could
  still render twice even with hideCurrentSnackBar — replaced with an
  inline error widget to sidestep the snackbar machinery entirely.

- register_screen now uses context.go instead of context.push for the
  OTP route, so re-submitting the phone form doesn't stack multiple
  OtpScreen instances with active subscriptions.

Lockout UX: AuthErrorInfo wraps the error message + code + retry_after_seconds
parsed from the backend's structured error response. On rate-limit codes
(OTP_COOLDOWN, OTP_RATE_LIMIT_PHONE, OTP_RATE_LIMIT_IP), the OTP screen
extends "Kirim ulang kode" cooldown to match the server's wait, and the
register screen disables "Kirim OTP" with a "Coba lagi dalam …" countdown.
formatCountdown() in core/constants.dart renders Xd under 90 seconds and
Xm Yd above (clearer than raw seconds for long lockouts).
