(chores): fix SonarCloud S6201 in multiple modules

[orpiske]

Summary

• Replace traditional instanceof check + explicit cast with Java 16+ pattern matching instanceof across 103 files in 14 module groups
• Addresses ~250 SonarCloud S6201 violations (pattern matching for instanceof operator)
• All changes are purely mechanical — semantically equivalent, no behavioral changes
• Note: The MailConverters semantic fix was removed from this PR and submitted separately in camel-mail: fix incorrect guard in MailConverters multipart loop #22340
• Note: Renamed pattern variable element → elem in DefaultCxfBinding.java to avoid shadowing (per review feedback)

Modules fixed:

• Core: camel-support, camel-core-model, camel-core-languages, camel-base-engine, camel-yaml-io
• AWS: camel-aws-bedrock, camel-aws-config, camel-aws2-ddb, camel-aws-secrets-manager, camel-aws-xray, camel-aws2-cw, camel-aws2-ec2, camel-aws2-eventbridge, camel-aws2-mq, camel-aws2-msk, camel-aws2-s3, camel-aws2-sns, camel-aws2-sqs, camel-aws2-sts, camel-aws2-translate
• Azure: camel-azure-functions, camel-azure-servicebus
• CXF: camel-cxf-common, camel-cxf-soap, camel-cxf-rest, camel-cxf-spring-soap, camel-cxf-spring-rest, camel-cxf-transport
• Components: camel-elasticsearch, camel-jackson3 (+avro, +protobuf), camel-mail, camel-netty, camel-netty-http, camel-opensearch, camel-pqc, camel-sjms, camel-smpp, camel-spring-rabbitmq, camel-zeebe

Test plan

• All affected modules compile with mvn -DskipTests install
• Formatting verified with mvn formatter:format impsort:sort
• CI passes on all affected modules

Good mechanical refactoring overall. 103 files, all pattern matching transformations are semantically correct with proper variable scoping. CI is green.

One change in MailConverters.java is a semantic improvement (not purely mechanical) — see inline comment. One nit on variable naming in DefaultCxfBinding.java.

for better readability when next users will have to read the git history, it will be better to have the real description inthe commit message as title and the Sonar ID reference only as part of the commit message body

Thanks for the feedback @apupier. Noted — future commits will use a descriptive title with the SonarCloud reference in the body only.
