Debit balance optimistically on pending send; pointer cursor on summaries

- Headline balance now shows wallet.total (confirmed + mempool) instead
  of confirmed, so a pending outgoing spend is debited immediately rather
  than waiting for confirmation. The chain_stats-based confirmed balance
  counts a coin as yours until the spend is mined, which is why it didn't
  drop after broadcasting (incl. scanned-tx broadcasts). Incoming pending
  is still surfaced by the "+X pending" line.
- summary { cursor: pointer } so the "Show QR" disclosure (and any other
  <summary>) shows the hand cursor.
