FEE: Add magic url for login

[shashilo]

Problem statement:
Users are more prone to login if they do not have to remember the password they chose.

Acceptance criteria:

• Implement the magic url API so users do not need to save a password.
• Add UX ability to login with magic url instead of username/password.
• Keep both options

Closing this issue as @shashilo and I found out about a bug that Appwrite has regarding triggering Appwrite functions when a new user is created from a magic url link or oAuth 2.0 link for authentication.
