Change the minimum transaction fee, or at least obtain that value from the connected server?

Given that our mempool is empty this season, we could potentially reduce the minimum transaction rate to less than 1.0 vbyte. However, I believe the correct approach would be to obtain the value from the connected server itself.

yes. since filters reduced to 0.1sats/byte minimum fee, we should reduced this limit also in this wallet.
