Avoid sensitive process arguments in gateway diagnostics

[Pigbibi]

Summary

• Avoid printing full container process arguments in gateway diagnosis and remote status; Java arguments can contain license or authentication material.
• Clarify that maintenance_enabled=false pauses scheduled redeployment only, and an all-skipped green workflow does not verify gateway or account health.

Evidence

• The current diagnostic workflow printed a Java process command line with a license argument during the 2026-09-25 read-only gateway diagnosis.
• The latest scheduled deploy selected no targets because all four have maintenance_enabled=false.

Scope

• No gateway restart, credential change, strategy switch, or trading operation.
