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.

+# Hyperliquid Testnet Wallet Setup
+
+To run the strategies on Hyperliquid Testnet, you need a wallet
+with testnet USDC. Here's how to set it up.
+
+## 1. Create a wallet (if you don't have one)
+
+Hyperliquid uses standard Ethereum wallets. You can generate one:
+```bash
+# Using Python (never use this key on mainnet!)
+python3 -c "
+from eth_account import Account
+acct = Account.create()
+print(f'Address: {acct.address}')
+print(f'Private Key: 0x{acct.key.hex()}')
+"
+```
+
+Or use any Ethereum wallet you already have (MetaMask, Rabby, etc.)
+
+## 2. Deposit on mainnet first
+
+The testnet faucet only works for addresses that have deposited
+on Hyperliquid mainnet. Send a small amount of USDC to your
+address on mainnet (app.hyperliquid.xyz).
+
+## 3. Get testnet USDC
+
+Go to https://app.hyperliquid-testnet.xyz/drip and claim
+1,000 mock USDC. You can claim once every 4 hours.
+
+## 4. Set the environment variable
+
+```bash
+export HYPERLIQUID_TESTNET_PK=0x_your_private_key_here
+```
+
+## 5. Verify
+
+```bash
+curl -s https://api.hyperliquid-testnet.xyz/info \
+  -H "Content-Type: application/json" \
+  -d '{"type":"clearinghouseState","user":"YOUR_ADDRESS"}'
+```
+
+You should see your testnet balance in the response.
