feat(rwallet): timeline-first UX overhaul with proportional rivers

- Fix USD estimation: add NATIVE_APPROX_USD price table for ETH, MATIC,
  BNB, AVAX, xDAI, CELO, GNO; unknown tokens fall back to $0 instead of
  raw token amounts (fixes wildly wrong river widths)
- Fix scroll hijacking: only intercept Ctrl+wheel (pinch-to-zoom) on
  timeline, flow chart, and sankey; normal two-finger scroll passes through
- Collapse address bar to compact chip after wallet loads with Save/Change
- Promote watchlist as horizontal chip selector above dashboard; merge
  example wallets as dashed "suggested" chips when watchlist is empty
- Default to timeline view after wallet detection (auto-loads transfers)
- Move balance/transaction tables to Details modal (pill button, overlay
  with backdrop blur) — stats cards hidden in viz views since D3 shows them
