fix: add missing type import

src/components/alert/Alert.vue

 <script setup lang="ts">
 import { useColorOrPastel } from '~/composables/colors'
+import type { PastelProps } from '~/types/common-props'
 
 const props = defineProps<PastelProps>()
 const color = useColorOrPastel(() => props.color, 'blue')
