feat(web): add Spring HTTP client and server logging

[youngledo]

Summary

• reorganize Spring HTTP logging and RestClient APIs by abstraction level
• add shared query removal, header/JSON redaction, and capped body-description policy
• add monotonic outbound duration and transparent synchronous/async Servlet logging
• auto-configure inbound Web MVC logging with a disabled-by-default NONE registration
• add focused, real Boot, AOT, and Native Image verification
• synchronize English and Chinese documentation
• remove the previously completed request-validation planning artifacts

Compatibility

This intentionally introduces a source and binary package break without compatibility aliases:

• org.jfoundry.web.spring.HttpLoggingLevel -> org.jfoundry.http.spring.HttpLoggingLevel
• org.jfoundry.web.spring.HttpLoggingInterceptor -> org.jfoundry.http.spring.client.HttpLoggingInterceptor
• org.jfoundry.web.spring.RestClientSupport and its error types -> org.jfoundry.web.spring.client.*

ProblemDetailRenderer remains in org.jfoundry.web.spring. Outbound logging still defaults to BASIC; inbound logging defaults to NONE.

Verification

• mvn -pl jfoundry-runtime/jfoundry-spring/runtime/jfoundry-web-spring -am test
• focused Web MVC and outbound auto-configuration tests
• focused six-module Spring Web reactor test
• mvn -pl jfoundry-runtime/jfoundry-spring/jfoundry-spring-integration-tests -am -Pit verify
• mvn validate
• GRAALVM_HOME=<graalvm> bash scripts/verify-runtime-ci.sh spring --stage native
