Fixed multiple critical issues reported by user:
1. **API Configuration Errors:**
- Fixed all API files to use correct config path (config/config.php instead of config/db.php)
- Fixed: get_users.php (bulk assign dropdown now loads users)
- Fixed: get_template.php (templates now load correctly)
- Fixed: bulk_operation.php (bulk operations now work)
- Fixed: assign_ticket.php (manual assignment now works)
2. **Dark Mode Improvements:**
- Added dark mode support for Activity tab content
- Ensured proper text and background colors in dark mode
All APIs now properly:
- Load configuration from config/config.php
- Use correct session variables ($_SESSION['user']['user_id'])
- Create and close database connections properly
- Return proper JSON responses
