kang 48349e3302 feat: Enhance settlement and draw management functionality
- Implement error handling for skipped settlement runs in DrawSettlementRunController, returning appropriate error messages based on draw status.
- Add validation in DrawPublishService to ensure draws are ready for publication, rejecting outdated result batches.
- Update SettlementBatchWorkflowService to revert ticket statuses upon settlement rejection and restore jackpot pool amounts.
- Refactor LotteryTransferService to improve transaction handling for transfer order reconciliation, ensuring idempotency during reversals.
- Add multi-language support for new error messages related to settlement processes.
