New paper_trades table (migration 007) + service/router. "Mark as taken" on each setup card (shares prefilled from position sizing, entry from current price, both editable) records a simulated trade. Overview gains an Open Trades table that marks each position to the latest close — P&L in $, %, and R-multiples — with a total unrealized P&L footer and a Sell button to close at the current price. Closed trades are retained for future realized-P&L reporting. Deploy: alembic upgrade (new paper_trades table). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
