Add live dashboard with WebSocket PnL streaming, deploy at ftdt.io/cv

Built a tasteful dark-themed dashboard showing real-time strategy
performance. Components:

- dashboard/server.py: FastAPI + WebSocket backend that collects
  strategy metrics and streams them to connected clients
- dashboard/static/index.html: Clean single-page dashboard with
  equity curve (Chart.js), per-strategy PnL cards with Sharpe,
  win rate, drawdown, and a live trade log
- Deployed as a background process on port 9175, proxied by Caddy
  at ftdt.io/cv via handle_path

Also added docs/WALLET_SETUP.md with step-by-step instructions
for setting up a Hyperliquid testnet wallet and claiming faucet USDC.

Design: dark theme, JetBrains Mono for numbers, Inter for labels,
status dots with pulse animation. No bloat — one HTML file + vanilla JS.
