Node Split beta

[pigmej]

This is the next phase after #337

1. API Changes and Architecture:

   • Remove local function calls in favor of HTTP-only calls
   • Support monolithic application using two goroutines (node and smesher service)
     • Add a warning that this combined mode might be deprecated.
   • Implement communication between services via localhost

2. Service Refactoring:

   • Begin with node directory refactoring
   • Focus on distinguishing between bootstrapper, node service, and activation service modes
   • [node-split] Single binary, multiple commands. go-spacemesh#6618

3. API Improvements:

   • Ensure Node Service API is CDN compatible
     • Use hex for input
     • Prefer path-based access over query strings
   • Implement GET requests node-split-poc: Move smeshing identities to v2beta1 go-spacemesh#6648
   • Add pagination and filtering capabilities to states API node-split: smesher states api filtering & pagination go-spacemesh#6613
   • Enable filtering of events by type node-split: smesher states api filtering & pagination go-spacemesh#6613
   • Implement pruning capability for old events
   • Introduce v2beta1 and migrate v2alpha1 POST API calls to GET go-spacemesh#6630
   • Convert node service API responses from binary to JSON go-spacemesh#6623
   • Transfer total slots calculation to smesher service go-spacemesh#6624

4. State Management:

   • UI to deduce per-epoch state and execute the API calls
   • Carefully manage epoch state retrieval, particularly for coinbase from previous ATX
     • we need to ask proper epoch ATX to get information about rewards (n-1) otherwise we may endup with wrong coinbase
   • Create documentation explaining state retrieval and understanding
   • Allow event duplication for UI purposes

5. Documentation:

   • Create visual documentation (Excalidraw) for state management and understanding
   • Documment config changes and adjust official docs

6. UX / UI

   • Add versioning support on the first screen smesher-app#17
   • Versioning for node-split #340

Remove current 100-item limit from smesher states
Add pagination and filtering capabilities to states API

I think it's also valid for eligibilities and proposals endpoints (in SmeshingIdentitiesService):

@pigmej This can be removed:
Remove current 100-item limit from smesher states
The limit was removed along with the introduction of persistent data.
