[Fix] Increase max wait time for server readiness to accommodate model loading

[AndyZhou952]

PLEASE FILL IN THE PR DESCRIPTION HERE ENSURING ALL CHECKLIST ITEMS (AT THE BOTTOM) HAVE BEEN CONSIDERED.

Purpose

Fix #1029 example 10 and follow-up to #1075 . This is introduced by switching to the common OmniServer from test.confest with default max_time=600s (In the CI use case, we increase the time to 1200s to accommodate that in the previous PRs, but it was overwritten - we revert the changes here)

Loading safetensors checkpoint shards: 67% 2/3 [07:35<03:42, 222.93s/it]ERROR/usr/local/lib/python3.12/dist-packages/coverage/control.py:958: CoverageWarning: No data was collected. (no-data-collected); see https://coverage.readthedocs.io/en/7.13.2/messages.html#warning-no-data-collected

Is there some other issue besides the maximum waiting time?
