This pull request introduces improvements to configuration retrieval and caching mechanisms, as well as updates dependencies and enhances test reliability. The main focus is on optimizing how configuration data is fetched by leveraging caching, and ensuring tests reflect cache state changes.

Caching and configuration retrieval improvements:

• Refactored resolveConfigByKey in src/aggregator/resolvers.js to first attempt fetching configuration from cache using getConfigFromCache if caching is enabled, falling back to a database query otherwise. This improves performance and reduces database load.

Testing reliability and cache consistency:

• Updated tests in tests/client-api-cached.test.js to explicitly refresh the domain cache after changing configuration status, ensuring that test results are consistent with the latest cache state. [1] [2]

Dependency updates:

• Upgraded the express-rate-limit package from version 8.4.1 to 8.5.0 in package.json to incorporate the latest fixes and features.
