Summary
• Swapped out the obsolete `<Spin>` loader for a modern, animated Semi-UI `<Skeleton>` implementation in `UsageLogsActions.jsx`.
Details
1. Added animated Skeleton placeholders mirroring real Tag sizes (108 × 26, 65 × 26, 64 × 26).
2. Introduced `showSkeleton` state with 500 ms minimum display to eliminate flicker.
3. Leveraged existing `showStat` flag to decide when real data is ready.
4. Ensured only the three Tags are under loading state - `CompactModeToggle` renders immediately.
5. Adopted CardTable‐style `Skeleton` pattern (`loading` + `placeholder`) for consistency.
6. Removed all references to the original `Spin` component.
Outcome
A smoother and more consistent loading experience across devices, aligning UI behaviour with the project’s latest Skeleton standards.
