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.

Backend: adds JDBC session support, login/status/logout endpoints, and
new DTOs (AuthResponse, ConnectionStatusResponse, LoginResult). Frontend
replaces the Vite boilerplate with a Dashboard, ServiceCard, and
ConnectModal backed by a typed API client.
