Fix two stale failing tests

- TestHandleAPIBenchmarkPowerFitRampQueuesBenchmarkPowerFitTasks: ramp-up
  mode intentionally creates a single task (the runner handles 1→N internally
  to avoid redundant repetition of earlier ramp steps). Updated the test to
  expect 1 task and verify RampTotal=3 instead of asserting 3 separate tasks.

- TestBenchmarkPageRendersSavedResultsTable: benchmark page used "Performance
  Results" as heading while the test looked for "Perf Results". Aligned the
  page heading with the shorter label used everywhere else (task reports, etc.).
