wrapped the main navigator with a component that will take the current auth status and pass in to the navigation component so that it does not rerender until the state has changed

tranfered the whole current logic of authentication inside the authentication context and expose only method to interact with it.

add a button in the profile screen to logout the user. currently he's not being returned to the authentication screen

using appstate to listen to browser closing. Current implementation is wack tho. waiting for the api to be fixed to handle response properly

decoupled the function; add a checkStatus function that will do the job and return a string if an errror occured

KeyboardAwareScrollView made good work of raising the form inside the curved container when focused. Also added an offset so that the input field is always a little above the keyboard
