app: centralize kind→icon in one KIND_ICONS map

Every surface hand-mapped deployment kind → lucide icon, so they could (and did) drift. Add KIND_ICONS/kindIcon to lib/labels beside kindLabel, and route KindBadge (→ all detail headers/cards/sections), the Overview tiles, and the program links through it.
