fix(ci): set management.server.port=0 in test profile to fix 25-min test timeout

Port 8081 was fixed by #576. With four @DirtiesContext(AFTER_EACH_TEST_METHOD)
classes (22 context restarts total), the OS TIME_WAIT state holds port 8081
for ~45-60s per cycle — adding ~17 min overhead. All 1601 tests pass but
surefire's 10-min timeout fires before the suite finishes.

Fixes #593.
