[Feature Request] Optionally hide server startup banner

Is your feature request related to a problem? Please describe.

Currently it seems start_local (hopefully I'm not getting the source wrong) would by default show a startup banner (which is not useful in test I assume, and would pollute test log), e.g.:

tests/workflows/test_workflows.py::TestProcessUploadWorkflow::test_complete_upload_processing 
CLI 1.4.1 (Server 1.28.0, UI 2.39.0)
Server:  localhost:39163
Metrics: http://localhost:36885/metrics
PASSED
tests/workflows/test_workflows.py::TestProcessUploadWorkflow::test_processing_loop_multiple_levels CLI 1.4.1 (Server 1.28.0, UI 2.39.0)
Server:  localhost:44607
Metrics: http://localhost:42807/metrics
PASSED
tests/workflows/test_workflows.py::TestProcessExampleUploadWorkflow::test_example_upload_processing 
CLI 1.4.1 (Server 1.28.0, UI 2.39.0)
Server:  localhost:38181
Metrics: http://localhost:44591/metrics
PASSED
tests/workflows/test_workflows.py::TestEditUploadMetadataWorkflow::test_successful_metadata_edit 
CLI 1.4.1 (Server 1.28.0, UI 2.39.0)
Server:  localhost:38509

Describe the solution you'd like

It would be great if this banner could be suppressed by default (or at least have a switch to mute it)?

Additional context

Start at the start_local entry point and inspect the workflow tests under tests/workflows/, where the banner output is shown. Determine how startup output is emitted and verify that the requested default suppression or mute switch prevents the banner from polluting test logs.
