chore(dashboard): drop dead reportDashboardPerf client and its log file

The /_perf/dashboard-load server route no longer exists, so every
reportDashboardPerf() call was a silently-swallowed 404. Remove the helper
in legacy.ts plus its five call sites in App.tsx / useProjects.ts (the
companion console.log lines stay), and drop the dashboard-perf.log entry
from the test-isolation runtime ignore list since nothing writes that file
anymore.

+Remove the dead `reportDashboardPerf` client and its five call sites in
+`App.tsx` / `useProjects.ts`. The companion server route `/_perf/dashboard-load`
+no longer exists, so every call was a silently-swallowed 404. Also drops the
+`dashboard-perf.log` runtime ignore-list entry from
+`scripts/check-test-isolation.mjs` since nothing creates that file anymore.
+Console-side perf logging via `console.log("[App] …")` and
+`console.log("[useProjects] …")` is preserved.
