Add AI rerank and detail actions to Components V2

[Mbeaulne]

Tophatting

Manual tophatting recommended because this adds AI reranking and detail actions.

1. Turn on the Components V2 beta flag.
2. Open /components-v2 and search for a component.
3. Select a result and confirm the detail panel opens.
4. Close the detail panel with both the close button and Escape.
5. Configure Agent Settings, then try the AI rerank button.
6. Copy a component and paste it into a pipeline if testing the full editor flow.

What changed

Adds the final interactive pieces to Components V2:

• AI rerank button
• AI unavailable/error states
• component detail panel
• copy-to-clipboard action
• analytics ids for detail actions

Why

After normal search finds matching components, users can optionally ask an LLM to rerank those results. The detail panel lets users inspect a result without leaving the page.

Test plan

• Turn on the Components V2 beta flag
• Open /components-v2
• Search for a component
• Select a result and confirm the detail panel opens
• Close the detail panel with the close button and with Escape
• Configure Agent Settings and confirm the AI rerank button becomes usable
• Click AI rerank and confirm results update or an error message appears
• Copy a component and paste into a pipeline if testing the full editor flow
• Run pnpm exec vitest run src/routes/Dashboard/DashboardComponentsV2View.test.tsx
• Run pnpm run typecheck --pretty false
