feat(inspur): enrich storage serials from SOLHostCapture.log smartd output

When the BMC HDD API returns an empty array (RAID controller attached via
PCIe, e.g. PM8204-2GB), disk serial numbers are now recovered from smartd
startup messages in SOLHostCapture.log.

Enrichment runs in three passes: model-match on existing slots, positional
fill of empty backplane placeholders, then new entries for any remainder.
Both log/ and runningdata/var/ copies are merged with serial deduplication.

Parser version bumped to 2.1.
