PackagesStep: surface verified providers via 2-col MiniCard grid

The unverified-tier "similar packages" section previously rendered a list
of NearbyPackageCards — one per package. Swap to MiniCard, showing the
provider itself: image, verified badge, location, rating, "From $X".
2-col on sm+, 1-col on xs, capped at 4. Heading dropped "nearby" to
"Similar packages from verified providers".

Data shape renamed NearbyVerifiedPackage → NearbyVerifiedProvider;
`verified` is implicit (the section is verified-only by definition).
Callback renamed onNearbyPackageClick → onNearbyProviderClick, routing
directly on provider id. Demo fixture now derives the list from the
main providers fixture (filtered to verified + imageUrl).

NearbyPackageCard is now orphaned — kept in place pending registry
cleanup in a follow-up.
