Adds complete audit trail for all stock movements: - InventoryTransaction model with transaction types (reserve, fulfill, release, adjust, set, import, return) - Alembic migration for inventory_transactions table - Transaction logging in order_inventory_service for all order operations - Captures quantity snapshots, order references, and timestamps Each inventory operation now creates a transaction record for accountability and debugging. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
