Fix navigation on the Menu Screen

[thetimileyin]

At present, when users are on the 'menu screen/tab' and they carry out either of the actions on that screen ('Recovery phrase', 'Send testnet coins back' or 'About Padawan'), there is no 'back button' that takes them back to the 'menu screen' and even when they go back by default on their phones, it doesn’t still take them back to the menu screen they are coming from; it instead takes them the homepage which is the 'wallet' tab.

Describe the solution Fix the navigation such that when users go back from whatever tab from the 'menu screen' it takes them directly back to the 'menu screen' and not the 'wallet screen'

Additional/Alternative Solution Add a back button to each of those screens. For example:

I think we should fix the back navigation too because some users might use the native back button instead of the one present on the screen
