chore(code): rename "new product" to "new app" in user-facing copy

Per user feedback, "product" sounds too serious — "app" keeps the door
open for hackathons and weekend projects. Updated:

- Sidebar entry button under PromptInput
- Command palette entry ("New app" / "Create new app")
- Dialog title + loading curtain ("Create a new app", "Preparing your app")
- Inline error copy ("Failed to create app")
- Analytics action enum value (new-product → new-app)
- Scaffolding prompt phrasing the agent reads

Internal identifiers (file/component/store/feature names) keep the
existing "product" naming since they're not user-visible — renaming
them is churn for no UX gain.
