show fw version in hobbled mode
What changed, and why it matters
This commit simply adds a menu item that displays the device's firmware version in a restricted ('hobbled') mode. It is a user-interface enhancement with no security-relevant behavior change.
No security action needed; treat as a normal UI enhancement.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change adds one line to HobbledAdvancedMenu in shared/flow.py, exposing the existing show_version() function as a menu item labeled ‘Show Firmware Version’ (or ‘Show FW Version’ on non-QWERTY devices). The Next-ChangeLog.md entry classifies it as an enhancement. No code logic, cryptography, authentication, or access control is modified.
