Extract Row primitive, migrate all call sites

Variants card/ref/plain with scoped skin. Padding and wrap
one-offs via style prop; draggable and handlers via rest
spread. GroceryRow absorbs item-btn/ref-link globals with
local names; BestRef scopes best-ref. Delete item-* globals
and dead page overrides.
