fix(buscar): correct the gaps between the filter row and the results

Issue 3 (partial): the results area had no top gap against the filter

in another. Applies the 3-tier scale properly -- row tier for
background-less placeholders, card tier for card states.

The rest of the app's spacing review is still outstanding.

+/// with a bare `radio_rounded` icon. This widget is the ONE shared
+/// implementation every one of those call sites now uses instead.

+/// The selection formula is pinned EXACTLY as `TarjetaEmisora` originally
