test: improve JitsiTranscriptionStatus test with type safety and snapshot

Description

This PR improves the JitsiTranscriptionStatus Jest test with the following small but meaningful updates:

1. Added TypeScript type annotation for destructured exports to improve type safety.
2. Fixed minor formatting in the .withContext() message for cleaner console output.
3. Added a snapshot test for JitsiTranscriptionStatus to detect accidental changes in the exported object in the future.

These changes maintain backward compatibility while enhancing test reliability and developer confidence.
