refactor: Config persistence architecture

The architecture in the main process is split into 3 main parts:
* services: interfaces for services are injected into the stores through
  the MainEnv interface (for testability)
* services/impl: electron-specific implementations of services
* stores: the actions of the stores can invoke (asynchronous) services
