Improve import result message interface

Feature requests on the forum

Is your feature request related to a problem? Please describe.
Upon successful import, a null message is displayed, which is very difficult to associate with a successful import. And if import fails, the message {"message": "Internal Server Error"} is displayed all the time, which also does not say what the problem is.

Describe the solution you'd like
If import is successful, the message Import completed successfully! is displayed. And if import fails, a message is displayed that the import could not be completed, and the specific reason why (and also its solution is possible).

Describe alternatives you've considered

Additional context
The server should give the correct error messages, which can be displayed in the web interface to the user.

Good catch, been thinking about this before but never opened an issue. We'll implement this in aw-server-rust, which is destined to become the default server soon™.

@ErikBjare The datastore actually already returns the exact error in aw-server-rust, it's just a matter of sending it in the HTTP body response.

This would be slightly more complex (for a minor issue), but it would be great to stay on the same page, and instead just get the HTTP response in a box/alert that you can then close

This is now in progress here:

ActivityWatch/aw-webui#210

Next step is to return the actual error from aw-server and make the alert show that message, then we can consider this issue to be fixed. Right now it only says "Importing failed, see aw-server logs for more info"
