hailin 8326f8c35c fix(cdc): 添加 Debezium heartbeat 机制防止 WAL 堆积 
问题背景:
- PostgreSQL pg_wal 目录从 80MB 膨胀到 60.4GB，导致磁盘使用率达到 96%
- 根因: wallet/planting/referral 三个数据库的业务表长期无写入
- 虽然 Debezium 有 heartbeat 配置，但未配置 heartbeat.action.query
- 导致 replication slot 的 restart_lsn 无法推进，WAL 文件无法被清理

解决方案:
1. 在 wallet/planting/referral 三个服务中添加 debezium_heartbeat 表
2. 配置 Debezium connector 的 heartbeat.action.query
3. 每 60 秒自动执行 UPDATE 语句推进 restart_lsn

修改内容:
- wallet-service/prisma/schema.prisma: 添加 DebeziumHeartbeat model
- planting-service/prisma/schema.prisma: 添加 DebeziumHeartbeat model
- referral-service/prisma/schema.prisma: 添加 DebeziumHeartbeat model
- scripts/debezium/wallet-connector.json: 添加 heartbeat.action.query 配置
- scripts/debezium/planting-connector.json: 添加 heartbeat.action.query 配置
- scripts/debezium/referral-connector.json: 添加 heartbeat.action.query 配置
- 新增三个服务的 Prisma migration 文件

效果:
- pg_wal 从 60.4GB 降至 80.2MB
- 磁盘使用率从 96% 降至 40%
- replication slot lag 从 51-60GB 降至 KB 级别
