Aliases import

[ckiss]

ref

• All react source files moved from repo root to root/src folder
• Aliases to top level folders in src added to babel and tsconfig with support for assets, components, constants, hooks, services, providers, theme
• Import relative paths changed to use aliases
• Colors import added to theme's index.ts to have easy, combined import like import { text, colors } from 'theme'
• added missing type declarations for: react-native-easy-markdown, react-native-google-safetynet, react-native-ios11-devicecheck
• sorted imports: dependencies at the top and then local imports
