Retry on generating unique identifiers with MongoDB

This commit will mitigate write conflict:
```
org.springframework.dao.DataIntegrityViolationException: Command failed with error 112 (WriteConflict): 'Caused by :: Write conflict during plan execution and yielding is disabled. :: Please retry your operation or multi-document transaction.' on server xxx.mongodb.net:1026. The full response is {"errorLabels": ["TransientTransactionError"], "ok": 0.0, "errmsg": "Caused by :: Write conflict during plan execution and yielding is disabled. :: Please retry your operation or multi-document transaction.", "code": 112, "codeName": "WriteConflict", "$clusterTime": {"clusterTime": {"$timestamp": {"t": 1755758536, "i": 4}}, "signature": {"hash": {"$binary": {"base64": "xxx=", "subType": "00"}}, "keyId": xxx}}, "operationTime": {"$timestamp": {"t": 1755758536, "i": 4}}}
