feat(coverage): add Codecov Test Analytics with JUnit XML upload (#2968)

* feat(coverage): add Codecov Test Analytics with JUnit XML upload (RHIDP-11862)

Install jest-junit reporter at test time and upload JUnit XML results
to Codecov via codecov/test-results-action. Uses NODE_PATH to make the
reporter available without modifying workspace lockfiles. Test output
goes to runner.temp to avoid polluting the working directory.

* fix(coverage): use absolute path for jest-junit and pin version

Use absolute path to the reporter module instead of NODE_PATH for
robust resolution across different test runners. Pin jest-junit@17.0.0
for reproducibility and enable JEST_JUNIT_UNIQUE_OUTPUT_NAME to prevent
file overwrites in multi-package runs.
