Ran by filter on run dashboards now excludes automated CI runs

Previously, the “Ran by” filter on the cache, generate, Xcode build, Gradle build, test runs, and test case dashboards also returned automated CI runs alongside manual ones, even when filtering to a specific user. All six run dashboards now add an is_ci = false constraint whenever the filter is set with the equals operator against a user or account, so the results are limited to the runs that person actually triggered locally. CI runs are still reachable through the dedicated ci filter option.
