In Lua, 0 evaluates as truthy. The check
'if questLogEntry.isComplete then return questLogEntry.isComplete end'
was completely bypassing our fallback completion logic because
GetQuestLogTitle sets isComplete = 0 when a quest is incomplete.
This caused the arrow to still point to requiredSourceItems (like
the Cold Iron Key drops) because the quest was never being flagged
as 'isComplete=true' internally.
Fixed by explicitly checking for isComplete == 1 or isComplete == -1
before returning.
