Get rid of event system

[Zomis]

In retrospect, using a flexible event system was not a good idea.

Using a dynamic event-driven approach for everything...

• makes code very unreadable and confusing
• makes it difficult to figure out or troubleshoot "when A happens, B will happen"
• is still an interesting concept, somehow specifying "business requirements" in code is still intriguing to me (No I don't mean Cucumber. In the actual application, not just in tests)

Should be easier with The Big Refactoring™ #302

Using Koin can be an option: https://insert-koin.io/

Using SharedFlows would be similar to an event system but would be more Kotlin-ic. And would make supporting multiple coroutines/threads easier.
