feat: live data wiring (Alpaca/FMP) + strategy builder + screener

Wires the new dashboard to real market data and adds the strategy
builder & screener UIs that were stubbed in the previous commit.

Frontend (web/src/):
- lib/marketApi.ts: authenticated fetch helpers for chart bars,
  market indices, news, and FMP research endpoints
- views/HomeView.tsx: StockChart now fetches live OHLCV via
  fetchChartBars on symbol/period change with loading/error states;
  ResearchCards replaces the static placeholder with live FMP
  profile/metrics/earnings (next-earnings + last 3 historical)
- components/layout/Header.tsx: live SPY/DIA/QQQ price + change%
  via fetchMarketIndices, refreshing every 60s; removed unused
  static sparkline placeholder
- components/strategy/VisualRuleBuilder.tsx: drag-and-drop IF/THEN
  rule composer using @dnd-kit (RSI/MACD/EMA/Price/Volume,
  above/below/crosses, BUY/SELL with shares or % of capital);
  saves via POST /api/profiles
- components/strategy/CodeStrategyEditor.tsx: Monaco editor with
  JS strategy template; "Run Backtest" posts to /api/backtest and
  renders return/win-rate/Sharpe/drawdown plus trade log
- views/ResearchView.tsx: adds "Visual Builder" and "Code Editor"
  sub-tabs alongside Strategies / Signals / Backtesting
- views/ScreenerView.tsx: live FMP screener with market-cap and
  sector filters, sortable columns, click-to-load-symbol routing
- index.css: light theme background; @keyframes spin for loaders
- App.dom.test.tsx: rewritten for router-based AppShell (was
  asserting on the removed tab UI; fixes 5 prior failures)

Backend (backend/src/services/apiServer.ts):
- /api/chart/bars: detects crypto symbols (contains "/") and
  routes to Alpaca v1beta3/crypto/us/bars; equities use
  v2/stocks/{symbol}/bars with iex feed
- (existing) /api/news, /api/market/indices, /api/research/{
  profile,metrics,earnings}, /api/screener proxy endpoints

Build/config:
- web/vite.config.ts: dedupe react / react/jsx-runtime /
  react-router-dom so the vendored react-auth dist resolves the
  same React instance (fixes "Cannot resolve react/jsx-runtime"
  Rollup error)
- web/tsconfig.app.json: exclude shared/platform-clients.ts and
  shared/platform-mobile.ts (mobile-only, missing RN SDK)
- web/package.json: add react-router-dom, @monaco-editor/react,
  @dnd-kit/core, @dnd-kit/sortable, @dnd-kit/utilities

Verification: `npm run build` in web/ → clean (✓ built in 3s);
backend tsc --noEmit → clean. Test suite: 151/155 pass; the 4
remaining failures are pre-existing (3 useTabFeatureFlags module
cache leaks, 1 EntryForm), not introduced here.
