Follow up issue #117: use each module chip enum and the real Wi-Fi device, preserve flat-layout fallback on missing files, and handle allocation and size failures. Based on the report by ggorbi99-dev.
Declare the installed firmware and configuration paths on both USB modules so initramfs tools can include the matched set. Preserve failed system configuration and firmware-download errors instead of binding an interface after cleanup. Keep intentional reboot/re-enumeration returns unchanged.
Addresses #117. Validated with extracted probe regression cases, inventory/modinfo checks and all three modules built against Linux 6.8 and 6.17 headers; no Kylin boot hardware validation.
