feat(soak): Show the background jobs each round, and stop the loop spinning

Script B's monitoring loop had no pause at all - each round started the
instant the last one ended, so an overnight soak filled the log with
near-identical samples taken seconds apart. The section was even labelled
"Get data every 10mins" while running with no delay whatsoever.

The loop now ends each round with pause 60 and prints both job lists:
bgctl list for the platform job runner, jobs for anything the macro
backgrounded in that shell. A stress job that dies mid-soak shows up as a
shorter list on the next round instead of going unnoticed until the end.

60s is still hard-coded and the Status sheet asks for 10 minutes, so the
Phase 3 item stays open - this makes the loop sane, it does not close it.

Also adds docs/LTC2980_channel_map.csv: the nine settings/*.conf flattened
into one Board,CONN,Ch,NetName,Vnom sheet, generated by
tools/gen_channel_map.sh. The CSV is output, not source. NC channels are
kept as NC/- because the channel number is also the PMBus page - dropping
the gaps would shift every channel after them.

Two things the merged table makes visible: SWB0 and SWB1 carry identical
net names and voltages (only the bus and CB_I2C_CH differ), so those are
two copies that can drift apart silently; and there are exactly 8 NC
channels, all on CONN14/CONN15.

tools/100G_PRBS.txt, TR518.txt and fan_ctrl.txt join the existing
traffic_loopback_*.txt references. TR518 is not scripted yet and cannot
share the hardware with blanton_traffic_linespeed - both drive port
loopback and L2 learning.

Script A -> V1.0.10.
