feat(bolt): increase item limit in show_info_with_cancel
One info item occupies 2 paragraphs; the limit is therefore
increased from 4 to 18 items.
This is a preparatory commit.
[no changelog]
What changed, and why it matters
This commit changes the on-screen display component used by one user-interface helper from a short paragraph container to a long one, raising the maximum number of info lines that can be shown from 4 to 18. The commit message explicitly calls it a 'preparatory commit' and there is no indication of a security bug or fix.
No security action required. Treat as a normal UI-capacity refactor and review the follow-up commits that this preparatory change enables.
Security signals we found
No strong security signals were identified.
Evidence from the diff
In core/embed/rust/src/ui/layout_bolt/ui_firmware.rs, the show_info_with_cancel implementation switches from ParagraphVecShort::new() to ParagraphVecLong::new(). The comment notes that one info item consumes two paragraphs, so the effective item limit rises from 4 to 18. No bounds-checking, parsing, or trust-boundary logic is changed; only the UI buffer type is enlarged.
