Add ability for students to add other students as friends

[JJamesWWang]

Todo

• Display students' user profiles publicly so that others can add them as friends.
  • Modify the GET endpoint of user/settings so that it takes a user's id. It should now detect if the id is the current user's id and change its display accordingly.
  • Add a way to copy a share link to a student's profile. The share link should have the student's user id so that our route can use it to look up which student it is.
• Add an "Add friend" button to the profile page when others are viewing it.
  • This should be a view that creates a friend request for the other student.
  • Make this button say "Pending" if the student has already sent a friend request.
• Display "Friend Requests" on a student's personal profile page.
• From the "Friend Requests" view, allow the student to either add the friend or reject the friend request.
  • The accept view adds the friend if the student is not already a friend.
  • The reject view should remove the friend request if it exists.
• Display all friends on the profile page.
• Allow the student to remove friends
  • This should be a view that removes the friendship if it exists

1. Make a new page where users can search for or discover other users
   • For each user, add a 'Add friend' button
   • Show friend requests received (let user either accept / decline)
   • Show pending friend requests sent by the current user
   • Allow the user to remove existing friends

Add 3 new fields to the auth_user table

• current_friends (list of User ids)
• incoming_friend_requests (list of User ids)
• outgoing_friend_requests (list of User ids)

I think these features make sense. We just need to ask user for their permission if they want their profile to be publicly available on this new page. This permission toggle can be done in the user settings modal.

• current_friends (list of User ids)
• incoming_friend_requests (list of User ids)
• outgoing_friend_requests (list of User ids)

For modeling the relationship between them, we cannot directly store lists in a relational database.

Suggestion

We need to leverage ManyToMany relationship to model friends relationship.
For friend requests, we can create another table called FriendRequest and two fields from and to
