Subject: [PATCH] Fix backend 500 errors for event creation and system version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix system version endpoint to read package.json using fs instead of require
  - Prevents MODULE_NOT_FOUND error in Docker container
  - Uses path.join to find package.json reliably

- Fix event creation email queue error
  - Change email_type from 'creation' to 'gallery_created' to match template key
  - Update email_data to include all required template variables
  - Added missing created_at and updated_at columns to email_queue table

- Fix file watcher duplicate photo insertion
  - Add check to prevent re-inserting existing photos on backend restart

These fixes resolve:
1. 500 error when accessing /api/admin/system/version
2. 500 error when creating new events
3. Email queue processing errors
4. Photo duplication issue
