Add full Next.js autotrader app with SQLite persistence and live Tradovate data

- SQLite DB (better-sqlite3) with firms, account_configs, firm_fees, instruments tables
- REST API routes: firms CRUD, account configs CRUD, state, accounts, instruments
- Live Tradovate WebSocket client: login, sync, positions, auto-liq thresholds
- Dashboard (app/page.tsx): per-firm account list with balance, day P&L, days traded,
  target progress, and Dead/Inactive/Flat status based on Tradovate auto-liq floors
- Account detail page: objectives progress, daily P&L chart, consistency tracking
- Per-firm settings page: account configs and instrument fee management
- Dead detection uses trailingMaxDrawdownLimit - trailingMaxDrawdown from
  userAccountAutoLiqs; filters Tradovate sentinel value (999999999 = no limit)
- FIFO P&L engine with commission accounting for daily P&L history
- Removed manual maxLoss fallback in favour of live Tradovate auto-liq data
