feat: Automatic reconnection

[Druidblack]

Please check existing knowledge before opening an issue

• I have checked the documentation
• I have searched through existing issues and discussions.

Describe the new functionality

You can add a function that will automatically try to reconnect to applications. Now I see in the screenshot two applications to which the program has not reconnected.

For the JF application, there is no reconnect button.

Configuration Example

No response

Will you help implement it?

• I am willing to contribute code towards completing this feature
• I am willing to help test preview builds for this feature

MS already has automatic reconnection logic but it is somewhat limited in that it depends on the Source/Client state being partially "usable" IE connection tests are OK and authentication is OK.

#221 introduces new logic that expands this logic to allow entirely restarting a Client/Source "from scratch" (as if from startup) automatically. If it's possible for MS to automatically restart a failed Client/Source, it will. (It checks this on a 20 minute schedule)

You can try this out using the docker image foxxmd/multi-scrobbler:pr-221.

Please let me know if you see automatic reconnect behavior still failing (when it should succeed) or not attempting to reconnect.

WRT the reconnect button, #221 also fixes this but I will address that in the other issue #220
