fix: portfolio field mapping (shares→quantity, cash→cash_balance) and pipeline recursion limit

- Map backend Holding.shares → frontend quantity, include market_value/unrealized_pnl
- Map backend Portfolio.portfolio_id → id, cash → cash_balance
- Map backend Trade.shares → quantity, trade_date → executed_at
- Pass recursion_limit=100 to pipeline astream_events() to prevent GraphRecursionError
