[Quantum-Yeti]

Summary:
Implement a centralized "Ticket Hub" in the application to manage, track, and monitor tickets efficiently.

Features:

1. Ticket creation with fields:
   • Title
   • Description
   • Priority (Low / Medium / High)
   • Status (Open / In Progress / Resolved / Closed)
   • Date created / updated
2. Ticket listing and filtering:
   • Filter by status, priority, or assigned user
   • Sort by date created or priority
3. Ticket update:
   • Edit details
   • Change status or assignment
   • Add comments or notes
4. Notifications / Alerts:
   • Notify user via an alert set within ticket.
5. Optional analytics:
   • Dashboard for open vs. closed tickets

Acceptance Criteria:

• Users can create, view, update, and close tickets.
• Tickets are stored persistently in the SQLite database.
• Hub interface provides filtering and sorting capabilities.
• Notifications while program is running.

Rationale:
A Ticket Hub will centralize issue tracking within the application, improving workflow visibility and allowing better task management and quality customer support.
