OtpError now carries an optional details object; rate-limit branches in
checkRateLimits compute retry_after_seconds (cooldown delta for OTP_COOLDOWN,
window-roll-out delta for OTP_RATE_LIMIT_PHONE / OTP_RATE_LIMIT_IP) so the
client can disable Kirim OTP / Kirim ulang CTAs with a real countdown.
All four sendAuthError helpers (client, mitra, shared, internal) now surface
err.details and log unhandled (no statusCode) errors at level 50.
New GET /api/shared/config/otp returns the resend cooldown so the OTP screen
can gate the resend countdown without hardcoding.
