debug: add logging to diagnose admin pricing page issue

- Added immediate calls to checkDbStatus() and checkWritePermission() in base.html
- Calls happen right after function definitions, before DOMContentLoaded
- Added console.log statements to track function execution and API responses
- Removed duplicate calls from admin_pricing.html to avoid conflicts
- This will help diagnose why username and admin link disappear on admin pricing page
