Live-testing against a UICC without the EPS files (no USIM service 85)
and without the Kc files showed the runner aborting when EPSLOCI/Kc were
absent. write_binary/write_record now take an 'optional' flag: a missing
candidate file is logged as a skip step instead of failing the scenario
(store_epsnsc, real/dummy locations, churn and Kc writes). Also allow
POST /api/write to select by 'path' like /api/select and /api/read (the
netsim live test needed it to restore the captured file values).
