WW-5766 Support struts.scopedConstantProvider in Java-based configuration

[lukaszlenart]

Fixes WW-5766

Summary

Java-based configuration (StrutsJavaConfiguration) can now select a custom ScopedConstantProvider. Before this change the only way was to subclass ConstantConfig and override getAllAsStringsMap().

ConstantConfig gets a scopedConstantProvider field, mapped to struts.scopedConstantProvider in getAllAsStringsMap(). It has a getter and two setters, following the localizedTextProvider mapping. The class setter takes Class<? extends ScopedConstantProvider> rather than the file's usual Class<?>, so a wrong class is caught at compile time.

Tests

• ConstantConfigTest.testScopedConstantProviderToString: the key is absent until set, then maps to the bean name from either setter.
• StrutsJavaConfigurationProviderTest.testScopedConstantProviderSelectedThroughConstantConfig: a custom provider registered through beans() and selected through ConstantConfig is the one the container returns.
• StrutsJavaConfigurationProviderTest.testScopableConstantsBeanSatisfiesScopedConstantValidation: a ScopableConstants bean registered through beans() lets an XML package's <scoped-constant> pass startup validation. This already worked and had no test.

The two integration tests load providers in the same order as Dispatcher: default properties, struts-default.xml, the Java config, then StrutsBeanSelectionProvider. They don't use StrutsDefaultConfigurationProvider, because it binds ScopedConstantProvider under the default name. With that binding, alias() skips the constant, so the test could never see the mapping.

I checked that the tests aren't vacuous. With the map.put line removed, both mapping tests fail. With the ScopableConstants bean removed, the validation test fails with "declares scoped constant [sample.scopable], which is not scopable". The full core suite passes: 3446 tests, 0 failures.

Out of scope

• Package-level overrides in Java config. StrutsJavaConfiguration has no package concept.
• Other bean-selection constants that ConstantConfig doesn't map either (parameterAuthorizer, ognlGuard, proxyService, ...).
