The short version

What changed, and why it matters

This commit adds Dogecoin support for multi-signature wallet addresses in a hardware wallet firmware. It lets the device create Dogecoin multi-sig addresses and sort public keys before building the address. There is also a trivial whitespace change in a UI file. The changes look like normal feature work, but adding new address handling always carries a small risk of address-generation mistakes that could make funds hard or impossible to spend.

Recommended action

Review the new multi-sig address path with Dogecoin-specific test vectors, verify that sorted vs unsorted public-key ordering matches the wallet coordinator's behavior, and confirm P2SH prefix constants are correct for Dogecoin mainnet. Treat as routine feature hardening rather than an incident response.
