tests: mark test_search_shows_results_found as transient HEAD main

The search endpoint occasionally returns a page without 'records found'
when GN2 is under load or just restarted (cold query path).  The test
passes on immediate re-run.  Mark transient as a signal for future retry
logic (e.g. pytest-rerunfailures) rather than treating failures as
definitive.
