Codecov: Integrate coverage reporting

[Ayush8923]

Is your feature request related to a problem?
The frontend repository currently lacks Codecov integration, resulting in no automated code coverage reporting. This hinders tracking of test coverage changes and maintaining code quality standards.

Describe the solution you'd like

• Set up Codecov integration for the frontend repository.
• Ensure test coverage reports are automatically generated and visible in pull requests and branch builds.
• Facilitate monitoring of coverage trends and improve overall code quality.

Describe the enhancement you'd like

• Set up Codecov integration for the frontend repository so that test coverage reports are automatically generated and visible in pull requests and branch builds. This should help monitor coverage trends, enforce better testing practices, and improve overall code quality.
