Replace ad hoc local types with MCP SDK schema types across the Prompts
group components and PromptsScreen, per the v2 UX interfaces plan.
- PromptListItem: accept `prompt: Prompt` instead of flat `name`/`description`;
render `title ?? name` as primary label
- PromptControls: accept `Prompt[]` + `selectedName` instead of `PromptItem[]`;
no-op on clicking already-selected prompt; search includes title field
- PromptArgumentsForm: accept `prompt: Prompt` instead of flat props;
read `prompt.arguments` directly; display `title ?? name` as heading
- PromptMessagesDisplay: narrow type from `(PromptMessage | SamplingMessage)[]`
to `PromptMessage[]` per spec
- PromptsScreen: accept `Prompt[]` + `selectedPromptName` + `GetPromptState`;
derive selected prompt via `prompts.find()`; own `argumentValues` state
locally; reset arguments on tool switch
- Delete local `PromptItem`, `SelectedPrompt`, `PromptArgument` types
- Update all stories with real SDK `Prompt` fixtures
- Update ConnectedView PromptsActive story
