fix(ci): address CodeRabbit review comments on qdrant health-check

- Pin qdrant image from 'latest' to 'v1.17.0' for reproducibility
- Upgrade health-check from bare TCP to HTTP /healthz probe via bash TCP
  so the job waits for Qdrant to be fully serving, not just port-open
- Replace deprecated codecov/test-results-action@v1 with
  codecov/codecov-action@v5 using report_type: test_results
- Guard integration test step: skip gracefully when no test_*.py files
  exist yet (avoids pytest exit code 4 on empty directory)
