feat: Round 48 narrative systems improvements

- QuestSO: Add ValidateBranchCycles() DFS detection for branches[].nextQuest loop
- QuestSO: Mark three legacy prerequisite fields with v2.0 removal warning in Tooltip
- IQuestManager: Add QuestLockReason enum + QuestLockInfo struct (strongly-typed lock info)
- IQuestManager: Add GetQuestLockInfo() method to interface; GetQuestLockReason() now delegates to it
- IQuestEventSource: Add OnQuestStateChanged(questId, oldState, newState) unified event
- QuestManager: Implement GetQuestLockInfo(); fire OnQuestStateChanged on all state transitions
- DialogueManager: Add one-frame yield in HandleChoices before ShowChoices (skip-debounce fix)
- DialogueManager: Increment _playbackId in ForceEnd() to invalidate residual choice callbacks
- DialogueSequenceSO: Add UNITY_EDITOR debug log in TryGetActiveVariant on variant match
- WorldStateRegistry: Add OnBatchStateChanged event + BatchMark() batch-write API
- DialogueModule: List badge shows warning indicator for unconditional-shadowing variants
- DialogueModule: BuildVariantsCard shows logic mode (AND/OR) alongside flag conditions
