fix(api-docs): scope Cloud Serverless spec to supported endpoints, absolutify download links
- Rewrite info.yml description to list supported endpoints (write, query,
authorizations, buckets, orgs) and disclaim unsupported Cloud (TSM) endpoints
- Comment out unsupported Cloud (TSM) paths in spec, keeping 29 supported paths
- Convert orphaned Cloud (TSM) tags to x-traitTag with disclaimer
- Strip all Redoc-specific anchor links (#operation/, #tag/, #section/) from
spec descriptions and tags.yml — these break in the Hugo-native layout
- Fix product name: "InfluxDB 3 Serverless" → "InfluxDB Cloud Serverless"
- Add absolutifyLinks() to generate-openapi-articles.ts so static/openapi
downloads contain full URLs (https://docs.influxdata.com/...) while Hugo
pages keep relative paths
