Add override support to nevents jobs and use YAML anchors for shared variables

- Add DETECTOR_CONFIG_OVERRIDE and DETECTOR_VERSION_OVERRIDE support to .nevents template
- Use YAML anchors to define variables once and reuse in both nevents and timings jobs
- Ensures both job types write to and read from the same RESULTS_BASE path
