Respect disabled schematic trace auto labels

[tongzhen1]

Summary

• propagate schTraceAutoLabelEnabled into the schematic trace solver input
• skip solver-generated and fallback schematic net labels when auto labels are explicitly disabled
• add a regression test for board-level schTraceAutoLabelEnabled={false}

Fixes #2243
