feat(ttl): Wire BMC monitors into Script B/C, log BMC version in A

Script A: dump the BMC banner via `bmc-manager run 'cat /etc/issue'`,
and add the missing `wait` before `show boot`.

Script B: start bmc_monitor_ddr.sh and bmc_monitor.sh alongside the
host stress load.

Script C: stop both and dump their logs into the master log.

bmc_monitor.sh: INTERVAL_SEC 5 -> 10.

Known blockers, filed here so they are not lost -- this wiring does not
work yet as written:

1. `bmc_monitor.sh tail` runs `tail -n 50 -f`, which never returns.
   Script C blocks on the first one and never reaches CHECK Stress
   results, the traffic counters, or the final messagebox. It needs a
   non-following dump (cat) instead.

2. Both scripts are mode 100644 and are the first .sh here meant to be
   executed rather than sourced. do_start re-execs "$SCRIPT_PATH"
   __daemon directly, so the execute bit is required even when invoked
   through bash -- and a Windows -> USB -> DUT copy cannot carry it.
   A chmod +x is needed before the start calls, as Script B already
   does for mlucas-avx2.
