Add visual badges to distinguish v1-compatible and v2-compatible API
endpoints in the sidebar navigation. This helps users migrating from
InfluxDB v1 or v2 quickly identify which compatibility layer each
endpoint belongs to.
Changes:
- Add x-compatibility-version extension to compatibility operations
- Add externalDocs links to reduce verbose descriptions in specs
- Update generator to extract compatVersion and externalDocs fields
- Display colored badges (purple for v1, cyan for v2) in sidebar nav
- Strip redundant "(v1-compatible)" text when badge is shown
- Add hover tooltips explaining compatibility context
- Add YAML article data files for all InfluxDB products
- Add sidebar-nav.html partial for API navigation rendering
- Rename data directory from article-data to article_data for Hugo compatibility
- Remove obsolete JSON articles file
