fix: update imports for VueUse v14 compatibility (#8550)

Update imports for VueUse v14 compatibility:
- `toValue` → import from `vue` (dropped from VueUse v14)
- `MaybeRef` type → import from `vue` (dropped from VueUse v14)

These APIs were deprecated in VueUse v12 and removed in v14 in favor of
Vue's native exports.
