feat(config): Run the fans at full speed by default

FAN_SPEED 30 -> 100. A soak is a thermal test of everything except the
cooling, so the cooling should not be one of the variables in it. At 30%
a long run can throttle partway through, and throttled results read like
a different fault entirely.

Folded into V1.0.11 rather than bumping the version: the tag has not
moved on and this is the same delivery.

+**The fans now default to full speed**
+* `FAN_SPEED` in `config.ttl` is 100 instead of 30. A soak is a thermal test of everything *except* the cooling, so the cooling should not be a variable in it — and a DUT that throttles halfway through a run produces results that look like a different fault. Lower it deliberately if quiet operation is what you are measuring.

 **A failed NVM write still reported success**

 * **`margin_save` in any form writes NVM permanently.** A power cycle does not undo it. `margin_save all` and `margin_save blanton` do it to all 18 controllers at once. Run `margin_status_all.sh` first and never call any of them during a test run — the macros do not, and should not be made to.
 * **The 18 raw commands were verified on the DUT; the wrapper was not.** `margin_save blanton` issues exactly the sequence that was run by hand at the bench, and the packaging was tested against stubbed hardware, but the function itself has not been run on a DUT yet. Watch the per-chip lines the first time.
 * **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has; traffic and the readiness gate both follow them.
-* **Set `FAN_SPEED`.** It is applied at the start of every run.
+* **`FAN_SPEED` is now 100.** It is applied at the start of every run, so this build runs the fans flat out unless you change `config.ttl`. Expect the noise.
 * **Management connectivity is in use, not preserved.** Both management NICs are up and pinging — drive the run from the serial console.
 * **PRBS is still not wired into the macros.** Run `port_prbs_monitor.sh` by hand if you want it; the calls in A/B/C remain commented out.
 * **Two settings persist to `config_db.json`** and survive a reboot: LLDP is left disabled and the 100G uplinks are left configured. Restore them before the DUT moves on.
