merge: Address technical dept in topology view (#162)

This pull request aims to address some of the technical debt in the topology 
view of the OpenDC frontend.

* Add support for panning of the datacenter topology
* Isolate world coordinate space (world objects do not depend on camera scale or position)
* Split transpiled modules into a separate chunk to reduce deduplication
* Encode state in topology actions to reduce global state
* Restructure components per page
* Enable more ESLint rules through `eslint:recommended` ruleset
* Move page components in separate files.
