[SPARK-46887][DOCS] Document a few missed spark.ui.* configs to Configuration page

[dongjoon-hyun]

What changes were proposed in this pull request?

This PR aims to document a few missed spark.ui.* configurations for Apache Spark 4. This PR focuses only public configurations and excludes internal configuration like spark.ui.jettyStopTimeout.

Why are the changes needed?

To improve documentations.

After this PR, I verified the following configurations are documented at least once in Configuration or Security page.
