fix: Incorrect Import Path for Vue 3 Composition API

[famouswizard]

I've corrected the import statement for Vue 3's Composition API. The previous import was pulling ref and computed from @vue/reactivity, which is incorrect for standard Vue components. These should be imported from the main vue package instead.

Changes:

• Replaced @vue/reactivity with vue for the ref and computed imports.

This ensures the code follows Vue's recommended structure for single-file components using <script setup>.
