Show number of triggered orders in Stop Run alerts

Add the number of triggered orders to the Stop Run alert notification text.

Currently the alert message includes volume and number of stops, for example:

Stop Run BUY: 220 contracts, 4 stops, 5234.25 - 5235.00.

However, the indicator already tracks the number of orders triggered within a cascade, which is visible in hover tooltips during analysis.

Including this value directly in the alert message would make notifications more informative and reduce the need to open the chart to check the order count.

Example format:

Stop Run BUY: 220 contracts, 4 stops, 12 triggered orders, 5234.25 - 5235.00
