Add an optional fee field (decimal, precision: 19, scale: 4) to trades. Fee is included in the total amount calculation (qty * price + fee) for both create and update flows. The fee field appears on both the create and edit forms, defaults to 0, and auto-submits like other trade fields. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
