Faster WS reconnect; stop double-running the held-coin reconcile

- _scheduleReconnect now backs off exponentially from ~0.6s (was a flat 4s), so
  a first socket attempt that's transiently rejected retries fast — the wallet
  reaches Live in well under a second instead of ~4s. Backoff resets on open.
- refreshLive now stamps _lastPoll at its start, so a socket-open refresh and the
  poll-timer tick don't both fire reconcileHeld back-to-back on load. A cached
  load does one held-coin reconcile (verify coins still unspent + frontier check)
  instead of ~3x.
