fix: resolve test type not found warning for Java tests

[aseembits93]

Summary

• Add fallback logic in parse_test_output.py to try original_file_path lookup when instrumented_file_path lookup fails
• Default to GENERATED_REGRESSION test type for Java tests when type cannot be determined
• Add JaCoCo plugin configuration to Java test project pom.xml

Test plan

• Run codeflash --file src/main/java/com/example/Algorithms.java --function fibonacci --verbose and verify warning is resolved
• Verify existing Java tests still work correctly
