allowsConfigWrites
True when the current lockdown state does not withhold normal configuration writes.
No received lockdown status (None), explicitly disabled lockdown (Disabled), and an authenticated lockdown session (Unlocked) do not withhold writes on lockdown grounds. AwaitingResponse keeps write eligibility unresolved until firmware reports the next state; locked, provisioning, and authentication-failure states withhold admin access. Managed-device policy is intentionally evaluated separately by the presentation.
