Fix recursion-limit build failure in the new item-card renderer

Same class of bug as the earlier ResourceValue/AnswerRow one: impl
IntoView doesn't erase a component's concrete type within the same
crate, so nested <For> children closures need their own explicit
.into_any() at the call site, not just at the outer return - missing
it on the two new <For>s (item list, item-card-fields) overflowed the
query depth limit on release build. Verified locally with a full
`cargo build --release` this time, not just cargo check.
