fix: Remove duplicate atlas-toggle-btn ID (#1336)

## Summary
Fixed duplicate `atlas-toggle-btn` ID in index.html.

## Problem
There were 2 buttons with the same ID `atlas-toggle-btn`:
1. Line 168: Incomplete button with title="World Directory"
2. Line 176: Complete button with title="Portal Atlas"

The first button was incomplete (missing closing tag and content).

## Solution
Removed the duplicate and incomplete button (line 168).
Kept the complete button with title="Portal Atlas".

## Changes
- Removed duplicate `atlas-toggle-btn` button from index.html
- Now only 1 button with this ID exists

## Testing
- Verified no duplicate IDs remain in index.html
- No merge conflict markers found
- File is clean and ready for merge

Issue: #1336
