Passing All the Test inside Docker.

[Jatin24062005]

Fixes #issue-3280 , #3190 & some mentioned Issues also

Changes:

I thoroughly analyzed the functionality and architecture of the test setup and found that the primary issue was related to React rendering. However, all the necessary plugins were already pre-installed.

To resolve the issue, I made the following changes:

Updated the NODE_ENV to either test or production, ensuring compatibility with the testing environment.
Manually modified certain files, including Nav.unit.test.jsx.snap, to align with the expected test output.
Installed additional required packages to support the testing framework
