The short version

What changed, and why it matters

This commit removes a dedicated two-page 'confirm output with amount' screen and replaces it with two separate confirmation prompts for the address and the amount. It is a user-interface refactor, not a fix for a security vulnerability. The change does not introduce obvious security flaws, but it slightly alters how users review transaction details on newer Trezor layouts.

Recommended action

No immediate security action required. Treat as a normal UI refactor. If reviewing for release, verify that the new two-step confirmation still requires explicit user approval for both address and amount, and that automated device tests pass.
