refactor: consolidate test mock constants into shared Mockdata class

Moved Mockdata from the connection package to the root test package and
extended it with MOCK_USER, MOCK_PASS, MOCK_TITLE, and MOCK_DESCRIPTION
so all test modules share a single source of truth. Removed duplicate
inline constants from ConnectionControllerTest, HomeboxIntegrationTest,
and SearchControllerTest.
