Review — Clean up service details overview UI

Reviewed the diff against main. This is a focused, low-risk UI cleanup and it holds together well.

Verified

• All eight removed helpers (getLockedServerLabel, formatReplicaCompact, formatPlacementLabel, formatEndpointCount, formatDataSummary, formatBackupLabel, formatDeployScheduleLabel, lowercaseFirstLetter) and the now-unused imports (cronstrue, Cpu, HardDrive) have zero remaining references in the file — no orphaned calls or dead imports left behind.
• Helpers that were shared with the removed sections (formatInstanceSummary, getConfiguredReplicaCount, formatResources, formatPortSummary, formatCount) are all still defined and still used.
• Moving resource limits into the Instances section and dropping the Capacity / Data & ops cards is coherent; the request-graph default flipping to Total matches the reordered toggle (Total first, then RPS).
• The border-border / ring-0 class additions are purely cosmetic.

Result: No correctness or dead-code issues. LGTM 👍
