feat: implement new relationship model

[owengretzinger]

TL;DR

Refactored user relationship management to support multiple relationship statuses and tracking friendship dates.

IMPORTANT: relationships will now be stored differently in the DB

Now it's:

// collection of users
id: {
    createdAt: Date,
    displayName: string,
    username: string, 
    // subcollection of relationships
    relationships: [
        status: "pending" | "friends" | "blocked",
        friendsSince: Date | undefined,
    ],
}

So each user with have a subcollection of relationships.

What changed?

• Replaced boolean isFriend flag with a comprehensive relationship system
• Added new relationship types: 'pending', 'friends', 'blocked', and 'none'
• Introduced mockRelationships to store relationship data between users
• Updated user profile to display "Friends Since" date when applicable
• Modified user queries to include relationship information in responses

How to test?

1. View different user profiles to verify relationship status display
2. Check that "Friends Since" date appears for users who are friends
3. Verify friend management actions (add/remove) work with new relationship system
4. Confirm friends list only shows users with 'friends' status

Why make this change?

To provide a more robust relationship management system that supports additional states beyond simple friend/not-friend, while also tracking important relationship metadata like when friendships began.
