sample-followup: LA Walls/DWLC1059 tracked as known-unresolvable (TK-12119)

Add DWLC1059 (LA Walls pattern 23003) to known-unresolvable set — vendor has
no vid anywhere in the fleet, so sweep can't chase it. Bucket it as
noVendorMap (accounted/WARN) instead of leaked (FAIL). Canary verdict:
FAIL → WARN, leaked 1→0. Reversible: remove SKU from set or delete set entry.
