Enable Ollama integration tests in CI and rename report to Integration Test Report

- Install Ollama, cache models (qwen2.5:0.5b + nomic-embed-text), and start
  server in the Misc integration job for both workflow files
- Set OLLAMA_MODEL and OLLAMA_EMBEDDING_MODEL env vars so the 5 Ollama tests
  are no longer skipped
- Rename Flaky Test Report to Integration Test Report throughout (job names,
  artifact names, cache keys, file names, script titles/docstrings)
