Fix sout expansion in unbraced for-loop bodies

[Stuaarts]

Description

Fixes Apache NetBeans issue #5244. Java code templates such as sout were rejected when entered as the single-statement body of a for loop without braces.

The filter already supported FOR_LOOP and ENHANCED_FOR_LOOP, but it applied a loop-header closing-parenthesis check to the body as well. The fix uses the loop statement source position to distinguish body context from header context, preserving the existing header validation.

Tests

• ant '-Dcluster.config=basic' build (baseline passed)
• ant -f java/java.editor/build.xml test-single -Dtest.includes=org/netbeans/modules/editor/java/JavaCodeTemplateProcessorTest.java (passed)
• Manual test in rebuilt NetBeans IDE: original unbraced for body sequence expands sout to System.out.println("");
• Full java.editor unit suite: unrelated ComputeImportsTest CRLF/LF fixture failures on Windows; other suites passed

thanks, looks good so far!

We would require a proper email address in the commit header, you can check it by looking at the patch of the PR: https://github.com/apache/netbeans/pull/9595.patch

Github anonymizes the email address automatically if submitted via web interface, but there is a setting somewhere in your account options if you like to change it there. You can also fix the commit locally if you want. Once fixed you can force push into the PR.

(git commit --amend --author="Name <email@example.com>" --no-edit would change the mail of the last commit. git log to verify)

Its ok to edit the commit and force push into PR branches for this project, since we merge PRs as-is without squashing. So it should be only one commit before merge.

nitpick: feel free to use multi line Strings. The editor has a hint to convert to it.

(same for the other new test cases you added)
