The short version

What changed, and why it matters

This commit is a small user-interface improvement for Trezor's Solana message signing feature. When a message has multiple cosigners, the device now shows each cosigner's position number on screen so the user can more easily tell them apart. It does not change how signatures are computed or how security checks work.

Recommended action

No security action required. Treat as a normal feature/UI commit. Reviewers may optionally verify the new index arithmetic displays the intended cosigner positions across all device models and languages.

Security signals we found

01

UI-only change: no cryptographic, parsing, or authorization logic modified

02

No new input handling, memory allocation, or trust boundary changes

03

Test fixture hashes updated only for multi-signer Solana message tests, consistent with expected screen text change
