feat: Round 49 narrative systems improvements

QuestManager: extract CheckQuestDepsAndFlags shared method, simplify GetQuestLockInfo/CanAccept/MeetsPrerequisites; add GetQuestsInState+FilterQuests implementations; fix extra brace compile bug; add _pauseTimestamps logging; use actualDelta in ApplyAffinity event.

QuestSO: add depth>32 guard to HasPrerequisiteCycle and HasBranchCycle to prevent editor freeze on deep chains.

EventChainModule: replace FindObjectOfType with ServiceLocator.GetOrDefault in ForceExecute; add self-trigger flag detection (check 6) in ValidateAllChains using reflection.

DialogueVariantPreviewWindow: add matrix analysis section enumerating all 2^N flag combinations (N<=10) with table showing winning variant per combination.

WorldStateRegistry: LoadFromSave null guard on data.World sub-collections (P0 fix).
