Display full model name in card detail panel

[eltmon]

Description

When clicking on a card and viewing the detail panel, the model is displayed in a shortened form (e.g., "sonnet") instead of the full model name (e.g., "claude-sonnet-4-20250514").

Current Behavior

• Model shows as "sonnet", "opus", etc.

Expected Behavior

• Model should show the full name like "claude-sonnet-4-20250514"
• This provides better clarity for debugging which specific model version is being used

Location

• src/dashboard/frontend/src/components/IssueDetailPanel.tsx or wherever the card detail displays the model

Priority

Low - cosmetic improvement
