Feature: #92517 - Custom Namespace for ExtbasePluginEnhancer

See forge#92517


The Extbase Plugin Enhancer for Frontend Routing allows to either set extension and plugin OR to set namespace. If extension and plugin were given, those were used.

However, the namespace option is automatically constituted by the extension and plugin options, if not set intentionally, and is mainly used when overriding the custom extension and plugin options by a custom (usually shortened) namespace, so the namespace is now always respected and preferred if all three options are set.


If all of namespace and extension and plugin options are configured, the namespace option is now preferred within the Extbase Plugin Enhancer.
