Update import path for getMissingKeys function

[rudrodip]

location: app/(chat)/page.tsx

import { getMissingKeys } from '../actions'

The current import path for the getMissingKeys function is relative ('../actions'), which can become confusing and harder to maintain as the project grows. We should update the import path to use an alias (@/app/actions) for better clarity and consistency with the project's import conventions.

Using aliased import paths makes the code more readable and easier to navigate, especially in larger projects. It also makes it easier to refactor or restructure the project without breaking import statements across multiple files.
