What the PR changes

• New docs: Adds a best-practices section under RealtimeKit with guidance on video resolution, simulcast, and frame rate for different layouts (1:1 calls, podcasts, group grids, webinars, screen sharing).
• Sidebar fixes: Bumps sidebar.order on several RealtimeKit pages to make room for the new best-practices entry.
• Demo/dashboard link updates: Replaces legacy demo.realtime.cloudflare.com links with examples.realtime.cloudflare.com across index.mdx, faq.mdx, sdk-selection.mdx, and getting-started.mdx.
• Screenshots: Replaces outdated dashboard screenshots in public/images/realtime-agents/.

Issues found

• MEDIUM src/content/docs/realtime/agents/getting-started.mdx line 264: The PR touched this line but preserved a pre-existing style issue. It says "Click on the `Join` icon" — the style guide requires select (not click) for UI interactions, and icon/button labels should be bold, not monospace. I posted an inline suggestion to fix this.

Out-of-scope note

• The image paths in getting-started.mdx reference public/images/... rather than root-relative /images/.... This is pre-existing across the repo, but worth fixing in a follow-up since the PR is already updating those images.
