d.viti fdc033f334 fix: Remove corrupted HTML in shop-mode logo section
Fixed duplicate and malformed HTML tags in logo upload section:
- Removed duplicate <div x-show="logoColor"> opening tag (line 171-172)
- Removed orphan ></span> closing tag (line 190-191)
- Cleaned up color palette display section

The corrupted lines were causing layout issues where the logo section
wasn't properly closed before the vendor input fields.

Verification:
- project-mode.html: Already correct, div balance = 0
- shop-mode.html: Fixed, removed lines 171-172 and 190-191
- Docker build: Successful
- Both files now have properly structured HTML
