Add ownership warning to deploy --reset-data

The script now prints the chown command needed after pushing data,
since uploaded files are owned by admin and the web server can't
write to them. Updated docs to match.

 **Important deployment notes:**
 - Files in `data/` must be owned by the web server user (`my_webapp__2`) for PHP to write to them
-- If deploying with `--reset-data`, the uploaded files get admin ownership - the web server then can't edit them
-- Fix with: `sudo chown my_webapp__2:my_webapp__2 /var/www/my_webapp__2/www/data/inventory.json`
-- Adding admin to the my_webapp__2 group allows the deploy script to write while keeping web server access
+- Using `--reset-data` uploads files as admin — you must fix ownership afterward (the script shows the command)
+- If edits aren't saving, check ownership with `ls -la` and fix with:
+  `sudo chown -R my_webapp__2:my_webapp__2 /var/www/my_webapp__2/www/data/`
