fix(procurement): exclude speed=0 signals + consistent speed formatting

Reconciles Stock/Health working-tree WIP uncommitted since 2026-07-04:
- supply-squeeze: exclude speed_gbps=0 / unclassified speed_tier=0 from
  price-momentum and AI-cluster-demand signals
- dashboard: render transceiver speed via fmtSpd() (1600 -> 1.6T) in
  reorder-top, switch-compat, supply-squeeze, dead-stock-revival tables
