feat: Add log message at end of sync with stats (#17826)

This adds a log line at the end of a sync to summarize the number of rows, errors and warnings, mirroring what would normally be displayed by the CLI if `--log-console` is not used.

Example:

```
{
  "level": "info",
  "module": "cli",
  "invocation-id": "5b90c610-ff42-4f85-a018-02d472c049f3",
  "resources": 227,
  "errors": 0,
  "warnings": 0,
  "duration": "1s",
  "result": "Sync completed successfully",
  "time": "2024-04-30T11:27:42Z",
  "message": "Sync summary"
}
```
