seed-product-features: two more icon-matching tiers

- token-containment pass: theme words inside the card title
  (ManagementFoundation -> "Aetria management foundation")
- last-pair rule: a complete set (#icons == #cards) with exactly one
  icon and one card left over pairs them (FlexibleConnection,
  EndToEndEncryption, HighPerformance, 4KSourcetoDisplays, AVoverIP)
- genuine mismatches (aligo-workstation, EZ-TV Platform, AvediaPlatform
  Artio icons) still stay unmatched for the editors
