Feature 4: Implement Ticket Templates

Add ticket template system for quick ticket creation:

- Created TemplateModel.php with full CRUD operations for templates
- Added get_template.php API endpoint to fetch template data
- Updated TicketController to load templates in create() method
- Modified CreateTicketView.php to include template selector dropdown
- Added loadTemplate() JavaScript function to populate form fields
- Templates include: title, description, category, type, and default priority
- Database already seeded with default templates (Hardware Failure, Software Installation, Network Issue, Maintenance Request)

Users can now select from predefined templates when creating tickets, speeding up common ticket creation workflows.
