Detect and warn about conflicts between Rule Sets and property-wide restrictions

When a host applies a Rule Set with no check-in or check-out day restrictions, existing property-wide restrictions still apply. However, the calendar can show the Rule Set as applied without warning the host about the conflict. This can leave hosts believing that booking sites are receiving different settings from those actually in effect. Please consider showing an error when conflicting settings are applied, or a persistent warning on the calendar. The warning should explain which restrictions take precedence and how the host can resolve the conflict.
