Currently, failure steps in the scheduling history modal use the same subtle badge color as other steps, making it hard to distinguish failures at a glance.

Changes

• Apply error color (red) to the step name text and result text for failed steps
• Keep success/other steps in their current neutral style to avoid excessive color
• Ensure sufficient contrast in both dark mode and light mode

Context

Per APC sync discussion (2026-03-20):

• Kangmin Kwon suggested highlighting failure with red text or background color
• HyeokJin Kim agreed that failure-only highlighting is needed
• Jongeun Lee confirmed: apply error color to step name + result text for failure steps
• Consensus: only failure should be highlighted, not all statuses
