Incorrect Redis Data Source Naming and Test Helper Generation in CLI

[Tyagi-Sunny]

Describe the bug
The CLI currently has multiple issues related to Redis data source handling and test configuration:

• Incorrect Redis Name in Test Helper:
  The test-helper.ts file generated by the CLI includes an incorrect or default Redis data source name, which leads to broken test setup or runtime errors.

• Improper Redis Data Source Name:
  The Redis data source name used in the generated files is either missing or not following the expected naming convention, causing inconsistencies in the codebase.

• Incorrect .nycrc File Generation:
  The generated .nycrc file is either missing required fields or is incorrectly formatted, which impacts test coverage reporting.

• Datasource Name Missing or Incorrect:
  The actual data source files do not have the correct or expected Redis data source name injected, affecting application behavior and bootstrapping.
