Refactor App State Patterns

[skokenes]

Initiative
Refactor our application state patterns to a more consistent and standardized format that will allow us to write more maintainable and extendable business model code.

Checklist of Issues
To be updated by the assignee.

• Setup BusinessModelContext and Provider that components can read from for the Dashboard feature (@skokenes, feat: app business model context #2704)
• At Dashboard feature level, create some directory structure for storing actions and selectors (@skokenes, feat: unified actions selectors #2749)
• Sub-feature by sub-feature, pull out applicable actions/selectors into their own unit-testable files
• Existing dashboard store methods to be extracted out into unit-testable functions in directory from item 2?
• Move dashboard initialization into a top of feature method; don't load dashboard UI until store is initialized (@AdityaHegde )
