Lukasz Lenart 690c4c2737 WW-5626 cleanup follow-ups for @StrutsParameter JSON/REST enforcement (#1673)
* WW-5626 add ParameterAuthorizer#resolveTarget for centralized ModelDriven resolution

Move the ValueStack peek logic that derives the target object from action+ModelDriven
state out of ParametersInterceptor and into ParameterAuthorizer. Callers that need
both authorization and the resolved target (for downstream OGNL allowlisting) can
now call resolveTarget once and reuse the result.

* WW-5626 delegate ModelDriven target resolution to ParameterAuthorizer

Replace the inline ValueStack peek in ParametersInterceptor#isParameterAnnotatedAndAllowlist
with a call to ParameterAuthorizer#resolveTarget. The ModelDriven import is no longer
needed in this class.

* WW-5626 defensively skip non-String JSON keys in authorization filter

The (String) cast in filterUnauthorizedKeysRecursive threw ClassCastException
for any custom JSONReader producing non-String keys. Replace with an instanceof
pattern that debug-logs and skips entries whose key cannot be converted to a
parameter path.

* WW-5626 add real JacksonJsonHandler integration tests for @StrutsParameter filtering

The existing ContentTypeInterceptorTest uses mock ContentTypeHandlers, so its
requireAnnotations=true tests verify only that intercept() returns SUCCESS — they
assert nothing about which properties were actually filtered. These integration
tests use a real JacksonJsonHandler + a real StrutsParameterAuthorizer to verify
end-to-end property-level filtering for top-level annotated/unannotated properties
and nested properties at varying authorized depths.

The SecureRestAction fixture documents a semantic divergence: REST's recursive
copy authorizes each path level independently, so depth-0 authorization on the
top-level property requires @StrutsParameter on the setter even when nested
field access is the actual goal. ParametersInterceptor only requires the getter
annotation. This divergence is tracked for the Approach C refactor.

* WW-5626 make ParameterAuthorizer#resolveTarget a default method to preserve SAM

Making resolveTarget abstract broke ParameterAuthorizer as a functional interface,
which the existing JSON and REST plugin tests rely on for lambda-based stubs:
  interceptor.setParameterAuthorizer((parameterName, target, action) -> true);

The default returns the action unchanged — adequate for lambda test stubs whose
authorization decisions don't depend on the resolved target. The production
implementation (StrutsParameterAuthorizer) overrides this with the proper
ModelDriven value-stack peek.
