test: skip Java comparator tests when Maven is unavailable

KRRT7 · KRRT7 · commit be446cd8dee3 · 2026-04-09T12:06:26.000-05:00
The requires_java marker only checked for java binary but the tests
also need mvn to build the codeflash-runtime JAR. These 13 tests
were silently failing in unit-tests (masked by continue-on-error).
