Micro release with various robustness improvements

Added an error boundary high up in the component tree to catch server failures and runtime errors. The server heartbeat now enables the client to detect that the server has crashed and jump to the error page. Users can follow the link in the error page to go back to the application once they have restarted their server.

The dev docker images now use mm 5.0 and include support for Ubuntu 23.10.

The diagnostics generated by the s3 command panel got a few usability improvements.
