feat: HPE iLO support — profile, post-probe hang fix, replay parser fixes, AHS parser

- Add HPE iLO Redfish profile (priority 20): matches on manufacturer/OEM/iLO signals,
  adds SmartStorage/SmartStorageConfig to critical paths, sets realistic ETA baseline
  and rate policy for iLO's known slowness
- Fix post-probe hang on HPE iLO: skip numeric probing of collections where
  Members@odata.count == len(Members); add 4s postProbeClient timeout as safety net
- Exclude /WorkloadPerformanceAdvisor from crawl paths
- Fix replay parser: skip absent CPU sockets, absent DIMM slots, absent drive bays
- Filter N/A version entries from firmware inventory
- Remove drive firmware from general firmware list (already in Storage[].Firmware)
- Add HPE AHS (.ahs) archive parser with hybrid SMBIOS/Redfish extraction
