feat(ui): agents \u2014 AgentCard + AgentCardGrid + AgentCostView to shadcn

- AgentCard: antd Card/Badge/Tooltip/Button + @ant-design/icons Copy/
  Key/Warning/Delete \u2192 shadcn Card/Tooltip/Button + lucide Copy/Key/
  AlertTriangle/Trash2. Status dot (emerald/amber) is categorical and
  the file is added to .eslintrc.json overrides.
- AgentCardGrid: antd Skeleton \u2192 shadcn Skeleton. Empty state uses
  border-border + bg-muted/50.
- AgentCostView: @tremor Title + antd Descriptions \u2192 plain semantic
  two-column grid with bg-muted header column.
- cost_config_fields.tsx skipped \u2014 the form is still driven by antd
  Form.Item from the parent; defer to when the full Agents form is
  migrated.

Gates: TS \u2713 | Build \u2713.
