feat: Add CSRF tokens to all JavaScript fetch calls and fix XSS

Browse Source 
Security improvements across all JavaScript files:

CSRF Protection:
- assets/js/ticket.js - Added X-CSRF-Token header to 5 fetch calls
  (update_ticket.php x3, add_comment.php, assign_ticket.php)
- assets/js/dashboard.js - Added X-CSRF-Token to 8 fetch calls
  (update_ticket.php x2, bulk_operation.php x6)
- assets/js/settings.js - Added X-CSRF-Token to user preferences save
- assets/js/advanced-search.js - Added X-CSRF-Token to filter save/delete

XSS Prevention:
- assets/js/ticket.js:183-209 - Replaced insertAdjacentHTML() with safe
  DOM API (createElement/textContent) to prevent script injection in
  comment rendering. User-supplied data (user_name, created_at) now
  auto-escaped via textContent.

All state-changing operations now include CSRF token validation.
