Built-In Time Range Filters and Trend Visualization for Dashboards

Dashboards currently display only the results of the most recent run, with no option to filter by a broader time range or to view how results have changed over time. This enhancement would introduce built-in time range filters, such as Last Hour, Last 24h, and Last 7 Days, along with a trend visualization capability at the dashboard level. Customers would gain the ability to review historical performance and identify patterns over time, improving visibility into operational trends without relying on manual comparison of individual runs.
