ui: Simplify data fetching in frontend

This pull request aims to simplify the data fetching logic in the OpenDC frontend.
Previously, the frontend used Redux extensively to sync the server state with the 
client state, which introduced a lot of unnecessary complexity. 

With this pull request, we move most of the data fetching logic out of Redux and 
instead use React Query to perform the logic for fetching and caching API requests. 

* Move all server data except topologies outside Redux
* Use React Query for fetching server data
* (De)normalize topology using Normalizr
* Remove current ids state from Redux 
* Combine fetching of project relations
