ETT-1246 Requesting an OCN with spaces in it from the API returns a 403

[moseshll]

• Modify the .htaccess rewrite rules for the Bib API so that spaces are escaped and passed through to volumes.php
  • This should reduce or eliminate AH10411: Rewritten query string contains control characters or spaces from the logs
• Add a bail-out condition in volumes.php:
  • If a query term has been reduced to just whitespace, don't send to Solr
• Add a filter on all query terms:
  • Remove all spaces after any other normalization has taken place
  • The existing lucene_escape should take care of anything else that might throw Solr for a loop
• Behavior around when to return a 400 is unchanged. 400 is only returned when all of the query terms or fields are bogus. The return payload is sorta machine readable, e.g. {"message":"query 'something:70628581' is invalid"}
• Playwright tests for htid and cid queries with spaces; we can expect nginx & httpd behavior to be the same or similar -- where the Bib API is concerned -- now.
