storage report: add new-vs-used disk verdict, human-readable data units, collect smartctl -i

Disk report now ends with a Conclusion section judging a drive NEW/USED
against loose thresholds (<110% capacity written, <210% read, <7d
uptime, <30 power cycles), listing which ones tripped. Data
Written/Read in the Usage section now scale to TB/PB via
formatBytesHuman instead of always printing raw GB. storageSATCommands
now runs smartctl with -i so SATA/SAS reports get Model/Serial/
Firmware/Capacity, which the Conclusion needs to evaluate the
write/read criteria (previously only -H -A was collected).
