Add auto-trade scheduler with batch locking, commission gross-up, and sync gate

- Auto-trade scheduler fires every 60s; uses Promise.allSettled batch so no new trades fire while any position from the current batch is open
- Commission gross-up: read entryCommission from cash.realizedPnL after fill (fallback 2.5×contracts), grossTarget = target + 2×entryCommission
- Sync gate: TradovateClient.syncComplete flag; scheduler skips tick until every client finishes initial position/balance sync
- Contracts formula changed to Math.ceil so $1500 target = 2 contracts
- Removed all fee caching (perContractFees, recentFills, fillFee handler) from tradovate-class.ts
- Removed firm_fees table, getFirmFees, upsertFirmFee from db.ts
- Deleted instrument-configs API routes; removed Fees UI from firm settings page
- /api/instruments returns full {symbol, enabled}[] objects; dashboard filters to enabled-only for trade selector
- Added auto-trade, debug, orders, settings, and trade API routes
- Instrument selector on dashboard now driven by enabled instruments from DB
