1. Created zoho-admin.css (was missing, causing 404)
- Added styles for Zoho admin page layout
- Card styling, form tables, sync buttons, status messages
2. Fixed jQuery not defined on master-trainer pages
- Changed inject_inline_content hook from wp_head to wp_footer
- Ensures jQuery is loaded before inline script executes
Note: "message channel closed" error is a browser extension issue,
not a code problem (typically ad blockers intercepting message passing)
