feat(ttl): Read EEPROM, quiet LLDP and clear lpmode before traffic

Script A: `hpe-eeprom-tlv show --bus 4 --addr 0x50` after `show boot`, so
the board identity is on record next to the image it booted. The empty
Check History placeholder is dropped.

Script A and B: disable the lldp feature and `config save -y` before the
traffic stage, so the switch stops sourcing its own frames and the
loopback pair counters reflect only the injected burst.

Script B: `sfputil lpmode off` on Ethernet513/514 before reading their
status -- a transceiver left in low-power mode will not link.

Script A -> V1.0.5, with the history covering the Script B changes too,
per this project's convention of keeping one consolidated log in A.
