redfish: MSI support, fix zero dates, BMC MAC, Assembly FRU, crawler cleanup
- Add MSI CG480-S5063 (H100 SXM5) support:
- collectGPUsFromProcessors: find GPUs via Processors/ProcessorType=GPU,
resolve serials from Chassis/<GpuId>
- looksLikeGPU: skip Description="Display Device" PCIe sidecars
- isVirtualStorageDrive: filter AMI virtual USB drives (0-byte)
- enrichNICMACsFromNetworkDeviceFunctions: pull MACs for MSI NICs
- parseCPUs: filter by ProcessorType, parse Socket, L1/L2/L3 from ProcessorMemory
- parseMemory: Location.PartLocation.ServiceLabel slot fallback
- shouldCrawlPath: block /SubProcessors subtrees
- Fix status_checked_at/status_changed_at serializing as 0001-01-01:
change all StatusCheckedAt/StatusChangedAt fields to *time.Time
- Redfish crawler cleanup:
- Block non-inventory branches: AccountService, CertificateService,
EventService, Registries, SessionService, TaskService, manager config paths,
OperatingConfigs, BootOptions, HostPostCode, Bios/Settings, OEM KVM paths
- Add Assembly to critical endpoints (FRU data)
- Remove BootOptions from priority seeds
- collectBMCMAC: read BMC MAC from Managers/*/EthernetInterfaces
- collectAssemblyFRU: extract FRU serial/part from Chassis/*/Assembly
- Firmware: remove NetworkProtocol noise, fix SecureBoot field,
filter BMCImageN redundant backup slots
