[ISSUE #9633] Enable retry topic V2 by default to prevent name collision

V1 retry topic naming uses underscore as separator (%RETRY%{cid}_{topic}),
which is ambiguous because both topic and group names may contain underscores.
This causes different (group, topic) pairs to map to the same retry topic,
leading to cross-topic consumption and potential data leakage.

V2 naming (using '+' separator) already exists but was disabled by default.
This commit changes enableRetryTopicV2 default from false to true.

Existing V1 retry topics are still readable because
retrieveMessageFromPopRetryTopicV1 remains true (backward compatible).

Changes:
- BrokerConfig: enableRetryTopicV2 default false -> true
- KeyBuilderTest: 3 new tests demonstrating V1 collision and V2 correctness
