Widget: keychain-free fresh defaults — drop defaultResult(), auto-populate at entry time

The small-widget skeleton (fresh widget stranded on the placeholder while
the medium populated in the gallery) traced to the small intent's default
configuration resolution: FavouriteFuelQuery/WidgetFavouriteQuery
defaultResult() read keychain in the gallery-preview/fresh-add path,
failing the whole default config and leaving no timeline. Configured
widgets bypassed defaultResult (stored values → lenient entities) — the
exact favourites-works/cheapest-closest-doesn't split.

- Remove defaultResult() from both queries: fresh configs now resolve
  from the static @Parameter(default:) values through lenient
  entities(for:) with ZERO storage reads.
- WidgetFavouriteQuery.entities(for:) skips the keychain name lookup for
  id-only (empty station) values.
- Auto-populate moves to makeEntry: empty pinned favourite → first
  favourite of the fuel (same rendered result as the old sheet default).
- Sheet keeps the dependent picker via suggestedEntities() + dependency;
  fresh widgets show static defaults until picked (approved tradeoff).
