getActiveAccessLevelId
Active access level for a property. Returns the resolved accessLevelId backing the published UserRoleAccess. Returns "" (empty) when no role is mapped for the property — empty means "property default" (NOT deny). The fail-closed behavior lives in entity hasAccess resolution, not here.
Return
the active accessLevelId, or "" if no role is mapped
Parameters
propertyId
the property to resolve the active access level for
