Update Allowed Destinations Settings

PUT 
/api/settings/allowed-destinations

Update allowed destinations for the current tenant.

Replaces the stored allowed_destinations entirely with the submitted value (not a deep merge) — the UI always sends the full intended state. The submitted value is silently clamped to the parent tenant's effective allow-list, and any country codes removed by this save are cascaded down the descendant subtree (their stored settings are updated and their effective-allow-list caches invalidated).
