fix(core): fix overflowing text in Delizia bld
- these should not be visible in the regular user flow anyway since we
introduced interactionless update
[no changelog]
What changed, and why it matters
This commit shortens two on-screen text labels in the Trezor bootloader from 'INSTALL FIRMWARE' to 'INSTALL FW' and 'UPDATE FIRMWARE' to 'UPDATE FW'. The change is purely cosmetic, intended to stop the text from overflowing its display area. The commit message notes these screens are not normally seen by users because updates now happen without user interaction. There is no security fix here.
No security action required. Treat as a normal UI/layout fix.
Security signals we found
None identified. The change is a UI text truncation to prevent label overflow.
Evidence from the diff
The patch modifies two string literals in core/embed/rust/src/ui/layout_delizia/bootloader/mod.rs. It replaces ‘INSTALL FIRMWARE’ with ‘INSTALL FW’ and ‘UPDATE FIRMWARE’ with ‘UPDATE FW’ in the bootloader UI title logic. The diff is +2/-2 lines and only affects label text length. No logic, cryptography, memory handling, or trust decisions are changed.
