Make NWC budgets accumulate and travel across devices

onRequest handled every request against the connection object captured
at listen() time, so each spend was recorded against a stale snapshot —
spentToday restarted from the old value on every payment and the daily
budget never actually bound. The connection is now re-resolved from
stored state per request, which also stops serving a connection revoked
on another device mid-session. recordSpend now publishes the sync
snapshot so the spend (and the payment's movement + vtxo change) reaches
the user's other devices. Test: two payments must accumulate to 52.
