Fix CLI timeout issues in integration tests

- Increase default CLI timeout from 5s to 30s in config.go
- Fix error messages to match test expectations ("user/node not found")
- Smart lookup gRPC calls need more time in containerized CI environment

The CLI smart lookup feature makes additional gRPC calls that require
longer timeouts than the original 5-second default, especially in
containerized test environments with network latency.
