Add RPC usage dashboard with rate limit monitoring (#6733)

currently blocked by analytics API needing to go to prod

<!-- start pr-codex -->

---

## PR-Codex overview
This PR introduces a new RPC usage dashboard for monitoring requests over the last 24 hours. It adds new components for visualizing request data and enhances the existing layout to accommodate this functionality.

### Detailed summary
- Added a new `RPC` tab in the usage layout.
- Introduced `CountGraph` and `RateGraph` components for visualizing RPC data.
- Implemented API call to fetch last 24 hours RPC usage data.
- Enhanced `ThirdwebAreaChart` to support max limit display.
- Updated error handling and user feedback for API data fetching.
