🟡 Changes recommended

The type accepts invalid solid combinations, Vue validators incorrectly expect objects, and ASP.NET metadata still excludes combined values.

Keep DashStyle Vue constructor as String

packages/​devextreme-vue/​src/​polar-chart.ts:993

DashStyle is still string-valued; changing the Vue runtime constructor to Object makes valid strings such as dashdot fail prop validation. Keep String for this string-literal union.
