[PR] [SPARK-55780][UI] Replace PNG logo with SVG in Spark Web UI [spark]
yaooqinn opened a new pull request, #54562:
URL: https://github.com/apache/spark/pull/54562
### What changes were proposed in this pull request?
Replace the rasterized `spark-logo-77x50px-hd.png` (77×50px) with an SVG version in the Spark Web UI navbar and favicon.
The SVG is derived from the official [Apache Spark website logo](https://github.com/apache/spark-website/blob/asf-site/images/spark-logo-rev.svg), with the text fill changed from white (`#FFF`) to the original dark color (`#3C3C3B`) to match the light navbar background.
### Why are the changes needed?
- **Resolution independence**: SVG renders crisply on HiDPI/Retina displays without pixelation
- **Scalability**: No artifacts when the browser zooms or the layout resizes
- **Consistency**: Uses the same vector source as the official Apache Spark website
### Does this PR introduce _any_ user-facing change?
The logo looks the same but renders more crisply on high-DPI screens.
### How was this patch tested?
- `UIUtilsSuite` (8 tests) passes
- Manual verification: logo renders correctly in navbar and browser favicon
### Was this patch authored or co-authored using generative AI tooling?
Yes, GitHub Copilot was used.
