CLOSES #9

refactor: Renamed ButtonNew and InputNew to simple Button and Input effectively replacing the old ones.

refactor: UserProfileScreen. No more dependencies on Box/Text themes's components. Dispatch a redux action to disconnect the user.

feat: Payment processing using Wave as the payment gateway with navigation on QrCode screen upon valid initialization. User is given the possibility to verify the state manually with a button.

feat: Payment processing utilizing Orange Money as the payment gateway, with browser support and verification functionality activated upon browser closure.

This may need more work once the api is fixed.

feat: implemented a functional login screen leveraging redux store to automatically redirect to the home screen once successfully logged in.
