fix(connectors): confluence version metadata fallback and google drive maxFiles guard

- Confluence: use `version?.number` directly (undefined) in metadata instead
  of `?? ''` (empty string) to prevent Number('') = 0 passing NaN check in
  mapTags. Hash still uses `?? ''` for string interpolation.
- Google Drive: add early return when previouslyFetched >= maxFiles to prevent
  effectivePageSize <= 0 which violates the API's pageSize requirement (1-1000).
