staticaddr: expose tracked deposit availability
Build list and summary responses from tracked deposit records instead of
raw wallet UTXOs so RPC clients see the manager availability state.
Split unconfirmed value from confirmed deposited value in summaries.

Keep withdrawal and channel-open flows on confirmed inputs by rejecting
unconfirmed selected deposits in those paths.
