fix(db): enrich auto-mode static quests with learner objective payload

In 'auto' data-source mode, QuestieDB.GetQuest now overlays the
SavedVariables learner record on top of the static DB quest, filling only
nil fields and deep-merging objectives/objIndex. Fixes quests like 8325
where the shipped DB has only a stub record but QuestieLearner holds the
real objective mapping that the stub was blocking. Learner data never
overwrites a present static value, so it strictly enriches.
