P2 Badge Preserve actual exports in the partial mock

In this partial-mock example, the factory now returns only formatDate and the overridden generateId, so the other real exports from ../src/utils (getTimestamp, sleep, log) are no longer available from the mocked module. A user copying this “use the original module implementation alongside mocked parts” pattern and importing one of those original exports will not get the real implementation; import the actual namespace with the rstest: 'importActual' attribute and spread it before overriding generateId.

const utils = await import('../src/utils');
