Phase 2: Refactor Tools cluster to use MCP SDK types

Replace ad hoc local types with MCP SDK schema types across the Tools
group components and ToolsScreen, per the v2 UX interfaces plan.

- ToolListItem: accept `tool: Tool` instead of flat `name`/`title`
- ToolControls: accept `Tool[]` + `selectedName` instead of `ToolListItemProps[]`
- ToolDetailPanel: accept `tool: Tool` instead of flat props; use SDK
  `ToolAnnotations` (readOnlyHint/destructiveHint/idempotentHint/openWorldHint);
  use `ProgressNotification['params']` for progress
- ToolResultPanel: accept `CallToolResult` instead of `ResultContentItem[]`
- ToolsScreen: accept `Tool[]` + `selectedToolName` + `ToolCallState`;
  derive selected tool via `tools.find()`; own `formValues` state locally
- Delete local `ToolAnnotations`, `ResultContentItem` types
- Update all stories with real SDK `Tool` fixtures
- Update ConnectedView ToolsActive story
