refactor: implement unified client overloading system

- Create new unified `overloadClient` function that handles both log and call methods
- Simplify client initialization by directly overloading parent class instances
- Replace SyncClient with direct FileSyncer instance for cleaner file handling
- Standardize tracing context, local file handling, and evaluation context across all client types
