Feature 5: Implement Bulk Actions (Admin Only)

Add comprehensive bulk operations system for admins:

- Created BulkOperationsModel.php with operation tracking and processing
- Added bulk_operation.php API endpoint for bulk operations
- Created get_users.php API endpoint for user dropdown in bulk assign
- Updated DashboardView.php with checkboxes and bulk actions toolbar
- Added JavaScript functions for:
  - Select all/clear selection
  - Bulk close tickets
  - Bulk assign tickets
  - Bulk change priority
- Added comprehensive CSS for bulk actions toolbar and modals
- All bulk operations are admin-only (enforced server-side)
- Operations tracked in bulk_operations table with audit logging
- Supports bulk_close, bulk_assign, and bulk_priority operations

Admins can now select multiple tickets and perform batch operations, significantly improving workflow efficiency.
