fix(quest): Phase 1 compat — guard quest-log-aware frame unload

Prevent premature frame unloading for completed-but-logged quests:
- AvailableQuests: UnloadUndoable() guard on currentQuestlog
- DailyQuests: HandleDailyQuests() guard on currentQuestlog
- QuestieQuest: IsSafeToUnloadQuestFrames() helper + HideQuest() guard
- TooltipHandler: IsQuestFlaggedCompleted gated by currentQuestlog
- TrackerUtils: fallback IsComplete gated by currentQuestlog
