feat: Round 50 narrative systems improvements

IQuestManager+QuestManager: add FillQuestsInState/FillFilterQuests buffer overloads (no-alloc hot path); remove R49 duplicate implementations.

QuestGiver: cache current quest result (_cachedQuest/_cachedState/_cacheDirty) to avoid per-frame foreach in InteractPrompt; invalidate on OnEnable and Interact_Internal state changes.

IDialogueService+DialogueManager: add StartDialogue(..., Action onComplete) overload; callback fires once on ForceEnd (covers both normal end and interrupt); supports chained callbacks via += accumulation.

DialogueVariantPreviewWindow: add 'Copy CSV' button in matrix section; exports all 2^N flag combinations with winner column; handles N>10 guard and CSV-safe escaping.

WorldStateRegistry: add TryGetCategory(id, out category) reverse lookup for debug tools.

NpcSOEditor: new CustomEditor for NpcSO showing live nameKey localization preview in Inspector (green label or warning box if Key not found).
