Refactor server-side folder management implementation

* better OOP architecture
* dependency injection everywhere
* abstraction where it made sense
* SRP applied as much as possible
* added a bunch of tests for the new code
* REST API compatible to old implementation
* new code is not optimized
* old code was not removed
