refactor [NET-1645]: Clean-up tsconfigs for the cdn-location package

[mondoreale]

This pull request updates TypeScript configuration and build scripts for the cdn-location (primarily) and dht packages to improve type checking, project references, and test configuration. The main focus is on refining how different parts of the codebase are built and checked, especially for data generation and testing.

Changes

TypeScript configuration improvements:

• Added a new tsconfig.data-generation.json in cdn-location for type-checking the data-generation directory without emitting output, and updated the main tsconfig.json to reference it.
• Updated tsconfig.jest.json in cdn-location to only include the test directory, and changed project references to point to the local tsconfig.node.json and test-utils.
• Adjusted tsconfig.node.json in cdn-location to remove the reference to test-utils, keeping only utils as a reference.

Build and check script enhancements:

• Improved the check script in cdn-location/package.json to run type checks for both test and data generation configs, ensuring stricter type safety across the project.

Project references update for dht package:

• Changed dht package TypeScript configs to reference the entire cdn-location project instead of just its tsconfig.node.json, simplifying dependency management.
