Use link to cross-service-endpoint dashboard in allure reports and benchmarking workflow logs (#10874)

## Problem

We have links to deprecated dashboards in our logs

Example
https://github.com/neondatabase/neon/actions/runs/13382454571/job/37401983608#step:8:348

## Summary of changes

Use link to cross service endpoint instead.

Example:
