## PR-Codex overview
This PR enhances the `useNFTDrawerTabs` function by improving the owner address comparison for NFTs. It now uses the `checksumAddress` utility to ensure that both the NFT owner and the account address are valid checksummed addresses before comparing them.

### Detailed summary
- Added import for `checksumAddress` from `thirdweb/utils`.
- Updated the owner address comparison in the `useNFTDrawerTabs` function to use `checksumAddress`.
- Ensured that both `accountAddress` and `nft.owner` are checked for validity before comparison.
