## PR-Codex overview
This PR focuses on enhancing the `SupplyCards` component by updating how supply data is fetched and displayed, specifically by introducing the `startTokenId` and refining the calculation of unclaimed supply.

### Detailed summary
- Added `startTokenId` to the imports from `thirdweb/extensions/erc721`.
- Changed `claimedSupplyQuery` to `nextTokenIdQuery`.
- Introduced `startTokenIdQuery` for calculating the real total supply.
- Updated unclaimed supply calculation to use `realTotalSupply`.
- Adjusted loading states and displayed values for total supply and unclaimed supply.
