feat(inspur_legacy): new parser for pre-Kaytus Inspur onekeylog

Older AMI-BMC Inspur onekeylog archives (NF5466M5 / NF5280M5 generation)
opened to an empty result: they carry none of the files the inspur parser
keys on (no asset.json, devicefrusdr.log, selelist.csv or component.log).

New package internal/parser/vendors/inspur_legacy (vendor id inspur_legacy),
separate from inspur:
- binary IPMI FRU decode (FRU.bin) -> board identity
- Inspur_AssetInfoInventory.log -> CPU / memory / PCIe / PSU inventory
- events from Inspur_<model>_<serial>_IDL, sel.log, blackbox.log,
  MegaRAID raid0.log, and the flat AMI <severity>.log files
- no live sensors in this archive class -> recorded as a collection error
- BMC clock timestamps before 2010 dropped as un-set (1970 / ~2005 RTC)

Registry: add optional PrioritizedParser { DetectPriority() int } so a
confidence tie is broken by specificity. inspur_legacy returns 10 and also
declines (Detect 0) when modern Kaytus markers are present, so the two
Inspur parsers never fight over a newer dump.

Docs: ADL-065, 06-parsers.md, releases/v1.32.
