test(scheduler-sim-decision-trace): error-path trace scenarios with the real allocator

Browse source 
Task 6.2: injects plan-claims growth, snapshot, finalize, host-scan,
per-host uncommitted lookup, allocation-function and unknown-jobid
faults and asserts each traced outcome. Also fixes two deferred OOM
paths: a failed limit row keeps the host's verdict bits, and an array
listing that cannot be built is reported instead of silently truncated.
