Migrate static OGNL method access to action wrapper methods

org.openrewrite.java.struts.migrate6.MigrateStaticOgnlMethodAccess

Migrates OGNL expressions using static method access (e.g., @com.app.Util@makeCode()) to use action wrapper methods instead. Static method access is disabled by default in Struts 6 for security reasons.
