calmarg demo: raise ILE request_memory 8192->16384 (extrinsic sampler spikes)

8192 still held the wide ILE jobs ("over cgroup memory limit of 8192").  The cal draws
do NOT double here (they stay at 100); the memory driver is the AV extrinsic sampler
spinning toward --n-max 4e6 on pathological low-cal-n_eff points, accumulating sample
arrays past 8 GB.  Completers peak ~7.3 GB; 16384 (2.2x) covers the hard-point spikes
and still matches most GPU nodes (median ~27 GB RAM).  ILE_extr auto-gets 2x.
