contractcourt: fix taproot coop close db record bug

Browse source 
In this commit, we fix an issue with co-op closes for taproot channels. Before this commit, we'd think that the remote party broadcasted a state very far in the future, and try to execute DLP. The wallet would properly credit the settled funds, but we'd mark the close in the DB as a force close.

To fix this, we also watch for the RBF sequence number we use in this scenario.
