Mock jokes API call in tests to prevent CI failures

[Copilot]

• Create testdata file for joke API response
• Update jokes_test.go to use gock for mocking HTTP requests
• Verify tests pass with mock data
• Run full test suite to ensure no regressions
• Revert unrelated formatting changes to gitstatus_test.go

Summary

Successfully updated TestGetJoke to mock the API call to https://icanhazdadjoke.com/ instead of making live requests. This prevents test failures during GitHub Actions builds caused by network issues.

Changes made:

1. Created internal/apis/testdata/joke.txt with sample joke response
2. Updated internal/apis/jokes_test.go to use gock library for HTTP mocking (consistent with other API tests)
3. Added table-driven test structure following repository patterns
4. All tests pass successfully without making external API calls
