fix(sap-demo-java): suppress elapsedMs noise on replay

Keploy's HTTP recorder now persists upstream timeouts as synthesized 504
mocks with the original reqTimestamp (see task #185). On replay the mock
is served instantly (millisecond-level elapsedMs) while the recorded
response captured real ~26s SAP network latency, so body-diff on
elapsedMs continues to fail test-16.

Add elapsedMs: [] under globalNoise.global.body to suppress the diff.
Note: the existing timestamp: [] entry does not cover this — timestamp
and elapsedMs are distinct fields on different response objects, so an
explicit entry is required for the synthesized-mock flow from #185.
