Specter-DIY v1.10.5 fixes random number handling failure and weak change verification

In previous versions of Specter-DIY firmware, a hardware random number generator failure could be silently accepted as valid entropy, while transaction change was checked using metadata supplied by the computer without verification on the device itself — opening the way for a malicious host to substitute the change address. A warning check for mixing inputs from different wallets in one transaction, which had previously failed to trigger, was also restored. This affects Specter-DIY hardware wallet owners.
