fix(collector): surface RAID/HBA controller cards from Storage.StorageControllers[]

The RAID controller (XFusion XC170-M-8i / Broadcom SAS3808) never appeared
in inventory at all: it isn't listed in any Chassis/Systems PCIeDevices
collection on this BMC, and its dedicated Board resource link 404s (id
contains parentheses, same class of bug as the OCP NIC fixed earlier). Its
full identity -- model, firmware, BDF, vendor/device IDs -- was sitting
unread in the Storage resource's embedded StorageControllers[] array the
whole time.

Added parseStorageControllerPCIeDevice + collectStorageControllers to read
that array and surface the controller as a PCIeDevice entry, merged into
the existing pcie_devices list.
