Module risk_account_builder 

Risk Account Builder - Assembles Portfolio Margin inputs.

This service provides a unified way to build PM snapshot inputs by combining:

• BalanceProvider: Engine-owned runtime balances
• PortfolioService: Executed positions with cost basis
• OpenOrdersSource: Resting orders for PM calculations

Both UnifiedEngine (for order admission) and API handlers (for /risk/grid) use this builder, keeping UnifiedEngine out of the API hot path.
