User - Forgot Password Flow

Description

Let's implement a recovery flow for users who forget their passwords.

I used a gem for the password stuff, so there might be some functionality there already for this.
Place link on the login screen
- This brings user to separate page
When user submit's email, if it exists, they will receive email
If a user clicks the link in the email, it brings the user back to the app where they can set a new password
