[Test]:Missing unit tests for security and protocol mapping logic in ServerHelpers

The helper ServerHelpers contains core decision logic for mapping AsyncAPI security schemes and protocols to user-facing labels and Kafka connection settings, but currently lacks dedicated unit tests.

Affected file (exact path)

'asyncapi-react/library/src/helpers/server.ts'

**Why tests are required**

This file encodes business and protocol semantics, not presentation logic.
Failures here do not throw errors but silently produce incorrect security information in the UI.

Key logic that needs coverage;

Read asyncapi-react/library/src/helpers/server.ts and trace the security-scheme and protocol mapping branches, including the Kafka connection settings logic shown in the issue. Add focused unit tests for each relevant mapping and verify that the expected user-facing labels and settings are produced.
