in wallet with many hardware cosigners, pairing order should be smarter (pairing error, keystore, sign_transaction, multisig)

I'm doing a stress test 8 of 8 native multisig wallet with 8 different hardware devices.

Electrum 4.0.2 appimage on debian

One odd issue I've noticed when starting to sign a transaction is that it seems to roll through prompting to connect every device, but if I connect a device out of order (which is really hard to determine) then I get this error:

To be precise, in this setup there are 2 different coldcards and in order to sign with the "second" coldcard I have to click "no" on the first connection attempt and THEN plug in the "second" coldcard.

Maybe this is a big ask since I'm not sure how the logic works, but it seems like electrum should be smart enough to detect that the device is actually part of the key set.

I'll also note that I have not experienced this issue with Trezor or Bitbox but have with Ledger. It might just be that I've always plugged them in in the expected order.

Start with the sign_transaction and keystore entry points, then reproduce the 8-of-8 native multisig stress test using multiple hardware devices. Trace the pairing error when devices are connected out of order, including the Coldcard and Ledger cases; done means a device in the wallet's key set can be recognized without requiring the expected connection order.
