Pull request description:
Closes#24458 - the wallet always chooses 1 million sats as its change target, making it easier to fingerprint transactions created by the Core wallet. Instead of using a fixed value, choose one randomly each time (within a range). Using 50ksat (around $20) as the lower bound and `min(1 million sat, 2 * average payment value)` as the upper bound.
RFC: If the payment is <25ksat, this doesn't work, so we're using the range (payment amount, 50ksat) instead.
