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

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

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

default value for quick login (doesn't show on the screen put pressing the button will send those values in the request).
Will be removed.

when the credentials are good. make request to retrieve user informations before navigating to the home page for authenticated user.
