fix(ui): theme Test Cases list for dark mode

[shah-harshit]

Describe your changes

Dark-mode coverage for the AI-mode Test Cases list route (workstream open-metadata/openmetadata-collate#6459, ticket open-metadata/openmetadata-collate#6534).

The AI-mode Test Cases route (components/observability/DataQuality/TestCases), its table header, filters, and table shell already use adaptive semantic tokens. The single dark-mode gap was the dimension-count chip in DataQualityTab, which used the raw palette class tw:bg-blue-50. Raw palette classes do not invert in dark mode, so the light-blue background stayed fixed while tw:text-primary flipped to a light foreground → light-on-light, unreadable in dark.

Change

• tw:bg-blue-50 → tw:bg-utility-blue-50 (auto-inverts per colors.md §2.7). Light mode unchanged.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Checklist

• git diff --check clean; prettier clean
• Visual light/dark QA of the AI Test Cases list — pending (static-only change)

🤖 Generated with Claude Code

Confidence Score: 5/5

The PR appears safe to merge because the changed class is an established adaptive token and introduces no functional regression.

Summary

This PR fixes the dimension-count chip’s dark-mode contrast by replacing a fixed blue palette background with the adaptive utility-blue-50 semantic token.

• Preserves the existing light-mode appearance.
• Allows the chip background to adapt under .dark-mode.
• Makes no behavioral, data-flow, or API changes.
