Migrate Testing Framework from Jest to Vitest

[prayanshchh]

Is your feature request related to a problem? Please describe.
We are planning to migrate the testing framework in the admin repository from Jest to Vitest to leverage Vitest's compatibility with Vite and improved performance. The initial step involves setting up Vitest alongside Jest and testing with one file. If successful, further issues will be created to migrate tests incrementally.

Describe the solution you'd like
Set Up Vitest Configuration
Add an initial configuration for Vitest.
Ensure compatibility with the existing Vite setup in the admin repo.
Keep Jest configuration intact for now.
Write a test for a single file using Vitest to verify the setup.
Ensure the test passes without any issues.

Describe alternatives you've considered
