* Shuffle change output on hardware wallet sends
Hardware wallet BTC/LTC sends passed outputs to the PSBT/device in the
given order (change last), a position fingerprint. The outputOrdering
param was plumbed but ignored. Add orderOutputs() and apply it in both
buildHardwareWalletTransaction paths; set the send call site to shuffle.
Refs #3376 (the software send + RBF paths were covered by #3420).
* Shuffle change output on Bitcoin Cash sends
The BCH send path built via ForkedTransactionBuilder with
outputOrdering: none, leaving change deterministically last. The builder
shuffles natively and change is found by isChange, not position, so flip
it to shuffle (matches the BTC software path from #3420).
Refs #3376.
* Update cw_bitcoin/lib/electrum_wallet.dart
