fix(config): mark audit log options as needing restart (fixes #10099) (#10100)

### Testing

Change the `auditEnabled` option and you should get a prompt in the Web
GUI.
Restart and change the `auditFile` option, and you should get that same
prompt.

The prompt you should get is shown in the screenshots below.
