Implement Akita store system for the entire app

[alex-nemeth]

Implement Akita store system:

• Create a store, query and service for Budgets
• Create a store, query and service for Users/Auth
• Refactor current auth and budgets services to interract with the new akita states
• Refactor entire app so all the data that is passed as props from app to other components are instead taken directly from the state

Akita might be unnecessarily too complex of a solution for now.

For the global state, create more angular services instead.

If it's going to seem like a helpful thing to implement again in the future, reconsider.
