BUSINESS AGENT PRODUCT COLORS UPDATE v0.2.1

Do this in order. Keep a database backup first. Do not import schema.sql and do not repeat earlier migrations.

1. In phpMyAdmin, select the existing Business Agent database and import migration_add_product_colors.sql once.
2. In cPanel File Manager open ai.borshaweb.agency/api/products. Upload this ZIP's api/products/index.php there and replace the existing index.php.
3. Install Business-Agent-update-v0.2.1.apk over the existing app. Do not uninstall the current app first.
4. In the app open Products > Add product. Enter colors separated by commas, for example: Black, White, Blue. Save and check the product card.

This migration only adds an optional products.colors column; existing products and data remain.
