feat: adaptive BMC readiness check + ghost NIC dedup fix + empty collection plan-B retry

BMC readiness after power-on (waitForStablePoweredOnHost):
- After initial 1m stabilization, poll BMC inventory readiness before collecting
- Ready if MemorySummary.TotalSystemMemoryGiB > 0 OR PCIeDevices.Members non-empty
- On failure: wait +60s, retry; on second failure: wait +120s, retry; then warn and proceed
- Configurable via LOGPILE_REDFISH_BMC_READY_WAITS (default: 60s,120s)

Empty critical collection plan-B retry (EnableEmptyCriticalCollectionRetry):
- Hardware inventory collections that returned Members=[] are now re-probed in plan-B
- Covers PCIeDevices, NetworkAdapters, Processors, Drives, Storage, EthernetInterfaces
- Enabled by default in generic profile (applies to all vendors)

Ghost NIC dedup fix (enrichNICsFromNetworkInterfaces):
- NetworkInterface entries (e.g. Id=2) that don't match existing NIC slots are now
  resolved via Links.NetworkAdapter cross-reference to the real Chassis NIC
- Prevents duplicate ghost entries (slot=2 "Network Device View") from appearing
  alongside real NICs (slot="RISER 5 slot 1 (7)") with the same MAC addresses
