Per-Probe Device Error Visibility in PA Dashboard

The PA Dashboard currently allows users to identify unreachable devices from a given probe, but it does not provide a reverse view that lets users select a probe and see the devices reporting errors for that specific probe. This enhancement would add a probe-centric view to the PA Dashboard, listing configured probes alongside the devices experiencing errors under each one. Customers monitoring large environments would gain a more efficient way to isolate probe-specific issues across their device fleet, reducing the manual effort needed to correlate errors back to individual probes.
