fix(connectors): jira pagination signal and google-docs paragraph join

- jira: rely solely on absence of nextPageToken for end-of-results;
  data.isLast on /rest/api/3/search/jql is unreliable (JRACLOUD-95477)
  and the OR-with-isLast logic could truncate pagination early
- google-docs: strip trailing newline from each paragraph before
  joining so heading->body produces a single newline, not two
