🔧 refactor: Prevent Unnecessary Google Service Key Loading (#8287)

* 🔧 refactor: Improve Google Key Handling in `loadAsyncEndpoints`

- Enhanced logic to check if GOOGLE_KEY is provided, including user-provided checks.
- Updated service key loading mechanism to only attempt loading if GOOGLE_KEY is not provided.
- Added error logging for service key loading failures.

* 🔧 refactor: Enhance service key loading logic in `initializeClient`
