feat(examples): Add video-resource-server example

Demonstrates serving binary content (video) via MCP resources using the
base64 blob pattern:

1. Server fetches video from CDN
2. Returns as base64 blob via `videos://{id}` resource template
3. Widget fetches resource and plays in `<video>` element

Includes multiple video sizes for testing (1MB to 150MB).
