- 在 normalizeServiceEvent 中添加对多种 id 字段的支持
- 当事件缺少 id 时，使用 aggregateId + timestamp 生成备用 ID
- 在 withIdempotency 中添加 event.id 验证，避免创建无效记录
- 修复驼峰格式事件可能没有 id 字段的问题

The outbox_events table uses outbox_id as the primary key column name
(mapped from id in Prisma). When Debezium captures changes, the message
contains outbox_id field, not id. This caused all events to have
undefined eventId, resulting in duplicate detection treating all events
as duplicates after the first one.

- Use Prisma $transaction with Serializable isolation level
- Insert idempotency record FIRST, then execute business logic
- Unique constraint violation (P2002) indicates duplicate event
- All operations atomic - either fully commit or fully rollback
- Modified all handlers to accept transaction client parameter
- Removed old non-atomic isEventProcessed/recordProcessedEvent methods
This ensures 100% data consistency for CDC synchronization, which is
critical for financial data where any error is catastrophic.

- Use (sourceTopic, eventId) as composite unique key in processed_events
- Add sourceTopic to ServiceEvent for globally unique idempotency key
- Wrap all handlers with withIdempotency() for duplicate event detection
- Fix ID collision issue between different service outbox tables
This implements the industry-standard CDC exactly-once semantics pattern.

- Add isHeartbeatMessage to detect heartbeat messages (only have ts_ms field)
- Skip processing for heartbeat messages to avoid unnecessary warnings
