fix(confluence): prevent content erasure on page/blogpost update and fix space update (#3356)

- Add body-format=storage to GET-before-PUT for page and blogpost updates
  (without this, Confluence v2 API does not return body content, causing
  the fallback to erase content when only updating the title)
- Fetch current space name when updating only description (Confluence API
  requires name on PUT, so we preserve the existing name automatically)
