[Bug]: [Bug]: Hardcoded mock follower IDs in Friends page should be removed #186

Bug Description

🐛 Bug Description
In src/pages/Friends.jsx, mock follower IDs are hardcoded
using array indices for UI testing but were never removed —
causing fake followers to appear for every user.

📍 Location
src/pages/Friends.jsx — Line ~47

🔁 Steps to Reproduce

1. Log in with any account
2. Navigate to Friends page
3. See "Followers" tab shows 2 fake followers ❌

✅ Expected Behavior
Followers tab should show real followers from Firestore,
or show empty state if no followers exist.

❌ Actual Behavior
Every user sees 2 fake mock followers regardless of their
actual follower data.

💡 Fix
// ❌ Current broken code:
if (filteredDevs.length > 2) {
setFollowerIds([filteredDevs[0].id, filteredDevs[1].id]);
}

// ✅ Fixed code:
Remove the mock block entirely and fetch real
follower data from Firestore instead.
