Mobile - Store - Code refactoring

[dzinzyura]

Goal:
Introduce a refactored "Store" code for react-native app.

Affected metric:

• Ease of use
• Ease of data handling
• Code readability improvements

Description:
Refactor the react-native code as you suggested: take out types, functions and divide them by logic (for example, chat functions, user functions) and import them from one file - it will take up less space, will be more understandable for external users
