fix: merge conflict artifacts in index.html (#1336)

Malformed HTML from unresolved merge conflict:
- Duplicate id="atlas-toggle-btn" (two buttons with same ID)
- Missing closing tags on soul and mode-toggle buttons
- First atlas button had no content or closing tag

Fixed: removed duplicate, added proper closing tags, single atlas button.
