docs(helm): document default Spark UI ingress TLS and annotations

[rahul810050]

This PR documents the default Spark UI ingress TLS and annotations feature introduced in PR #2513.

Fixed issue: #2558

It adds:

• An explanation of Helm-level default TLS and annotation configuration
• Clear precedence rules between Helm and SparkApplication-level settings
• Practical Helm and SparkApplication examples

This makes the default ingress TLS configuration option easier to discover and use.
