feat(sdk): configure Lambda client timeouts

Add connection and socket timeout configurations to LambdaClient to improve reliability:
- connectionTimeout: 5000ms (5 seconds)
- socketTimeout: 50000ms (50 seconds)

This helps prevent hanging requests and provides better error handling for Lambda API calls.
