This PR adds the option to provide additional settings when importing a backup.
The ServerUtil has been expanded to support passing in the target url and backup passphrase when importing a backup.
Also clarified wording around the import passphrase as there are (at least) two passphrases related to imports.
This fixes#6640
This allows the FE to call the import with both `direct` and `temporary` set to `true` to import from a config without needing a second step.
Once the FE is updated to support this, we can keep the unencrypted passwords out of the FE during import-from-config
This PR adds the ability to subscribe to messages over a websocket.
To prevent polling data, the server can now push messages through the websocket, so the client can instantly update when new data is available.
The change is backwards compatible, still serving the status updates over the socket. If the client is providing the authentication token, it is auto-subscried to the legacy status message.
If the client is using the new authentication message, it needs to subscribe to get the status updates (and any other services it needs).
The event system has been extended to support new, and more accurate, events. This is the first step towards removing the general status update and the long-poll mechanism.
This also re-introduces the blocking marker, so the client can know if the operation is halted due to too many pending transfers.
Some endpoints have been moved to service implementations, to allow serving the exact same data from both endpoints and websocket.
This PR also updates the way the progress is handled, so that all transfers are returned to the client, and the transfer speeds for each transfer is calculated based on a small sample buffer, so the values are more accurate even if the program is paused during transfers.
