dedupeMemory keyed on slot before serial, unlike dedupeStorage/dedupePSUs
which both prefer serial. Some collectors (observed on MSI CG480-S6053 with
older BEE-SP versions — confirmed reproducible across multiple servers,
fixed in newer BEE-SP versions) report every memory module at the same slot
label ("DIMM 0") even though each has a distinct real serial. Slot-first
keying collapsed all of them into a single record on export — 16 real 32GB
DIMMs (512GB) reduced to 1, discarding 15 physical modules' worth of data.
Serial now takes priority, matching storage/PSU. Also add
disambiguateMemorySlots (same pattern as the existing PSU slot fix): when
multiple already-distinct DIMMs still share a slot label, renumber them to
"DIMM {n}" by ascending serial order so Reanimator can track them by
position and results are deterministic across re-imports.
Updated the existing dedup test (was asserting the old collapse-by-slot
behavior on a same-slot/different-serial case, which was exactly the bug)
and added a dedicated regression test for the collision case.
