Add quality of life intuitive keyboard shortcuts

[ryanzyi]

As an enhancement, we could add intuitive keyboard shortcuts as quality of life features.

Examples include:

• pressing the enter key on the login/signup views would then execute the appropriate use case when the input fields contain valid inputs.
• pressing the escape key on appropriate views (like CookThisOrReRoll, Favourites, etc.) executes the Finish use case to return the user to the main menu.
