docs(apollo-vertex): onboarding tour — docs page and live demo

[petervachon]

What this does

Adds the documentation page for the Joyride onboarding tour component, including a live interactive demo you can click through in the browser.

Stacked on #953 (provider + welcome modal).

What's included

• Live demo — a working tour triggered by a "Start tour demo" button. The tour runs on the docs page itself, stepping through the welcome modal, static previews, feature callout, and install snippet.
• Static previews — side-by-side renders of the welcome modal card and step popover card so you can inspect the design without running a tour.
• Full usage docs covering:
  • Defining tour steps (popover vs. modal type, selectors, placement)
  • Conditional step gating with waitFor
  • Persistence — how completed tours are remembered across sessions
  • The BrandingAdapter extension point for custom welcome modal images

What comes next

This is the final piece of the 3-PR stack. After this merges, product teams can install the component with a single shadcn command.

Test plan

• Docs page renders at /patterns/onboarding-tour-joyride
• "Start tour demo" button launches the tour
• Welcome modal appears first, then step popovers advance through all 5 steps
• Progress bars in the popover reflect the current step
• Tour does not reappear after completion without resetting state
• Static previews render in light and dark mode
• pnpm --filter apollo-vertex lint passes
