Some collectors (BEE-SP observed so far) report every PSU at slot "0". The
export itself already keeps every PSU as a separate record (dedupePSUs keys
on serial first), but Reanimator relies on slot to track installed position,
so PSUs sharing a slot value land in "other components" instead of being
tracked as PSU installations.
Renumber colliding slots to stable 0-based positions by encounter order.
This doesn't invent a serial or other identity — the PSUs are already
distinguished by serial — it only assigns the position field Reanimator
needs when the source failed to. Files where every PSU already has a
unique slot are unaffected.
