1. video-resource-server: Add missing server-utils.ts and fix import path
- Was importing from non-existent ../shared/server-utils.js
- Now correctly imports from ./src/server-utils.js
2. basic-host: Be resilient to individual server connection failures
- Use Promise.allSettled instead of Promise.all
- Failed connections are logged as warnings but don't crash the UI
- Only throws if ALL servers fail to connect
3. threejs-server: Add id to canvas for reliable screenshot masking
- Added id="threejs-canvas" to the canvas element
- Updated e2e test masks to use #threejs-canvas and .threejs-container
- Fixes flaky Three.js screenshot comparisons in CI
