feat(inspur): source-PRI timezone timeline, PPIN serial, NVMe fault storage status

Event ingestion now uses the source syslog PRI and an explicit-offset
timezone timeline instead of assuming host-local time. CPU PPIN is
exported as the source-backed CPU serial, and an active NVMe fault SEL
event promotes the matching drive's storage status.

See ADL-056, ADL-057.
