feat(netinfra): prep LACP conversion commands for cross-rack trunk [#369]

Browse Source 
The cross-rack trunk (ch1, 4×1G) between core-sw01 and tor3-stor is
still static mode=on — no failure detection if a cable dies. Adding
command files to convert both switches to LACP during Friday's
maintenance window. Core hash stays layer-2-3 (5448 hardware limit);
stor hash stays layer-2-3-4 (already set).

! #369/#394: Convert cross-rack trunk ch1 from static (mode=on) to LACP
! Switch: core-sw01 (Dell PowerConnect 5448, rack 5)
! WHEN: Friday maintenance window — BOTH switches must change together
! RISK: Brief storage-net outage during transition (seconds)
!
! Current: g13-g16 in ch1, mode=on (static, no failure detection)
! Target: g13-g16 in ch1, mode=auto (LACP active partner negotiation)
!
! NOTE: core-sw01 hash stays layer-2-3 (hardware limit — best available)
! tor3-stor hash stays layer-2-3-4 (already set)
!
! IMPORTANT: Run this SIMULTANEOUSLY with tor3-stor change.
! If one side is LACP and other is static, trunk goes down until
! both sides match. Plan for ~30s storage-net outage.

! Radlan CLI syntax (different from DNOS on core-sw01)
! Verify exact keywords on this switch first — 'show running-config'
! will show the current ch1 config to confirm syntax.
