Upgrade HtmlUnit and Selenium dependencies

HtmlUnit 5 moved its Cookie type to org.htmlunit.http, so
Spring Test's HtmlUnit integration now uses the new API.

Constraint: Keep HtmlUnit and htmlunit3-driver versions compatible.
Rejected: Upgrade HtmlUnit alone | driver requires HtmlUnit 5.4.0.
Confidence: high
Scope-risk: narrow
Directive: Keep HtmlUnit and the driver version aligned.
Tested: JAVA_HOME=/opt/homebrew/opt/openjdk@25 ./gradlew build
Not-tested: None
