Fix rageshakes not uploading if they are too long (#6075)

* Fix rageshakes not uploading if they are too long. The max log line size in the default rageshake server is `1_000_000`.

* Change upload order to ensure the current logs and the push rules are always sent.

* Add 'buffer' for unexpected log lines.
