docs: Record the V1.2.7 additions in Script A's history and release note

Browse Source 
Script 4_1, blanton_tr518_thermal.sh, blanton_multiphase_read.sh and
Script_User_Guide.md are added to the V1.2.7 block of Script A's history
and to docs/release-notes/v1.2.7.md, which V1.2.7 is re-released with.

# v1.2.7 — FDR on the cabled ports only, and the vendor NFC tool updated to v2.5
# v1.2.7 — FDR on the cabled ports only, vendor NFC tool v2.5, and a tester user guide
## ✨ New features
**`Script_User_Guide.md` — the tester guide, shipped in the package**
* Part 1: copying `Blanton_Script/` from a USB stick onto the DUT (mount, copy, `chmod +x`, CRLF check), every `config.ttl` setting, and what Scripts A, B and C run, step by step.
* Part 2: the usage of every tool in `Blanton_Script/`, including the full LTC2980 margin guide.
**`4_1_Blanton_Script_thermal.ttl` — Script 4 with an idle phase and the thermal tr 518 load**
* 300 idle rounds first (PMON snapshot, SWB0/SWB1 rail power, AMD CPU power), then `blanton_tr518_thermal.sh start` and the full-load loop.
* The full-load loop also logs `nvme smart-log` / `smartctl -x` every round and waits with a DUT-side `sleep 1` instead of `pause 60`.
**`blanton_tr518_thermal.sh` — `tr 518` with the thermal-test arguments**
* Same as `blanton_tr518.sh` (start / stop, `-u`, `-w`, `--no-wait`, `-n`), but runs
`tr 518 Scenario=6 Profile=2 portstopktszstride=1 Count=260 PktSize=603,218 CheckLinkTime=20 CheckDataTime=200 TestPhase=1`.
* Override the arguments with `TR_THERMAL_ARGS`, not `TR_TEST_ARGS`.
**`blanton_multiphase_read.sh` — read back the SWB multiphase VRMs**
* Reads the controllers `blanton_multiphase_margin.sh` writes (SWB0 = i2c-13/15, SWB1 = i2c-14/16): one row per chip with VOUT / VOUT2, IOUT / IOUT2, POUT (V × I) and TEMP, plus the total power per board.
* Every voltage and current is followed by the raw PMBus word in hex, e.g. `0.740(0x0128)`.

## ⚠️ Before you run
* **`4_1_Blanton_Script_thermal.ttl`, `blanton_tr518_thermal.sh` and `blanton_multiphase_read.sh` have not been run on the bench yet.** Check that `tr 518` prints `TR 518 TEST PARAMETERS` on both units the first time.
* **`4_1_Blanton_Script_thermal.ttl` has no teardown, like Script 4**: finish it with `blanton_tr518_thermal.sh stop` **and** `systemctl stop mlucas-amm`.
* **`blanton_multiphase_read.sh` names 0x21 / 0x22 PU105 / PU102** (from `blanton_pwr_data.sh`), the reverse of the PHYTILE mapping in `blanton_multiphase_margin.sh`; the totals are not affected. Do not run it while `blanton_multiphase_margin.sh` is writing.
* **Port 268 (ce0, 100G uplink) is not in the FDR list** — as before. Add it with `FDR_PORTS="...,268"` if FDR is wanted there.
* **The cabled-port list now lives in three scripts** — `blanton_traffic_linespeed.sh`, `blanton_ber_debug.sh`, `blanton_fdr.sh`. Change all three when the cabling changes.
* **Never put the NFC write flags (`--write-ndef`, `--set-location`, `--confirm-write`) in `NFC_ARGS`** — polling would rewrite the tag every round.
