fix(xfusion): emit OCP NIC ports with no serial so reanimator keys them by MAC

Browse Source 
Verified against reanimator/core: it keys a NIC component on serial → MAC →
synthetic(slot). A BMC dump carrying the card serial collapses both ports into
one serial-keyed component, while a live-CD bundle (no serial) keeps two
MAC-keyed components, so alternating the two sources produced a spurious
COMPONENT_REMOVED + 2x COMPONENT_INSTALLED every time. Emitting the per-port
NetworkAdapter entries with an empty serial makes both sources key on the port
MAC and yield the same two components. The card serial still reaches the export
via the FRU record and the legacy NIC entry.

Also records ADL-062 findings from reading the ingesting audit tool: it persists
only vendor/model/serial per component (no size/speed/link/clock/wattage), so the
remaining one-sided field diffs between the two bundles cannot generate change
events.
