#824 moved per-entry line fetching into a single paged journal_entry_lines
join query. #809's OB-exclusion test was branched before #824, so its mock
queue lacked that response — every later mock shifted by one and the #OBJEKT
projects loop read journal-line objects (no .code), throwing TypeError on main.
Adds the journal_entry_lines (allLines) mock with lines keyed by
journal_entry_id. Test-only; no production code change. Restores green main.
