chore(ai): remove ai window rate limit

- Simplified the layout of the usage overview card for better visual clarity.
- Removed the `StatCompact` component as it was no longer needed.
- Adjusted the size of the `UsageProgressRing` for a more cohesive design.
- Cleaned up unused variables to streamline the code.
