Enable EVP flagevaluation system tests for Java

[leoromanovsky]

Motivation

tests/ffe/test_flag_eval_evp.py covers the server-side EVP flagevaluation contract for SDKs. Java spring-boot has a passing branch-backed system-test run, so its manifest can move from missing_feature (FFL-2446) to the validated version and provide the Java system-test companion evidence for DataDog/dd-trace-java#11639.

Changes

• Enables tests/ffe/test_flag_eval_evp.py for Java spring-boot in manifests/java.yml at v1.64.0-SNAPSHOT.
• Leaves other Java weblogs marked irrelevant.
• Keeps this as a sibling language enablement PR stacked on the merged EVP flagevaluation system-test baseline.

Decisions

• This PR enables only the validated Java weblog; other languages are enabled by separate sibling PRs after their own local pass evidence.
• Java validation staged all branch artifacts used by the weblog: dd-java-agent, dd-trace-api, and dd-openfeature.
• Existing OTel metric coverage stays in tests/ffe/test_flag_eval_metrics.py.

Validation

System Tests

• Companion SDK PR: feat(openfeature): emit server-side EVP flagevaluation dd-trace-java#11639.
• Rebuilt weblog image contains BOOT-INF/lib/dd-trace-api-9999.jar and BOOT-INF/lib/dd-openfeature-9999.jar.
• TEST_LIBRARY=java WEBLOG_VARIANT=spring-boot ./run.sh +l java FEATURE_FLAGGING_AND_EXPERIMENTATION -k "test_flag_eval_evp" - PASS on 2026-06-20, 8 passed, 2627 deselected in 82.29s.
• Runtime: Agent 7.80.1; library java@1.64.0-SNAPSHOT+7f0cf1f0e0; weblog spring-boot; Linux aarch64.
