### What changes were proposed in this pull request? This PR aims to enable `spark.ui.contentSecurityPolicy.enabled` by default from Apache Spark 4.3.0. ### Why are the changes needed? The `Content-Security-Policy` (CSP) header provides defense-in-depth against XSS on the Spark UI. All UI pages already emit CSP nonces for their inline scripts, so enabling it by default hardens the Web UI out of the box. ### Does this PR introduce _any_ user-facing change? Yes, the Spark UI sets the `Content-Security-Policy` header by default. To restore the previous behavior, set `spark.ui.contentSecurityPolicy.enabled` to `false`. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling? Generated-by: Claude Fable 5 -- This is an automated message from the Apache Git Service.
