Automate Ironic release version detection with dynamic series mapping

Replace static version hardcoding with fully dynamic fetching from OpenStack
releases repository at build time. The website now automatically displays
the latest Ironic version and handles new release series without any manual
updates.

- Add dynamic series detection from OpenStack series_status.yaml
- Implement automatic series-to-version mapping (e.g., gazpacho → 2026.1)
- Add sourceNodes function to fetch latest release at build time
- Update index page template to use dynamic release data
- Add comprehensive fallback mechanisms for API failures
- Update CMS preview template with mock release data
- Add test script to verify dynamic detection works
- Remove all hardcoded series names and version mappings

The system fetches both series list and version mappings dynamically,
making it completely self-maintaining for future OpenStack releases.
Version is fetched once per build and baked into static HTML for optimal
performance.
