Track Specification: Per-Ticket Model Override (per_ticket_model_20260306)

Overview

Allow user to manually select which model to use for a specific ticket, overriding the default tier model.

Current State Audit

Already Implemented

• models.Ticket: Has no model_override field

• No UI for model selection per ticket
• No override indicator in GUI

Functional Requirements

• Add model_override: Optional[str] to Ticket dataclass
• Model dropdown in ticket UI
• Visual indicator when override active
• Reset button to clear override
