## PR-Codex overview
This PR primarily focuses on improving error handling and code clarity in the `apps/dashboard` project. It modifies the `package.json` script for development, enhances JWT response validation, and adjusts value handling in a hook for better consistency.

### Detailed summary
- Updated the `dev` script in `apps/dashboard/package.json` to remove `--turbopack`.
- Added error handling for missing JWT in `apps/dashboard/src/@/constants/thirdweb.client.ts`.
- Changed return value handling to ensure it returns a `BigInt` in `apps/dashboard/src/app/(dashboard)/(chain)/[chain_id]/[contractAddress]/_components/claim-conditions/claim-conditions-form/hooks.ts`.
