When absMetadata (metadata.json) is the highest-priority source and a field is null, propagate that null into bookMetadata so lower-priority sources (e.g. audio file tags) cannot overwrite a value the user intentionally cleared. Previously all null values were skipped, causing cleared fields like subtitle to be repopulated from file tags on rescan.
