🔧 chore(demos): improve taco-aa-signing demo build tooling and code quality

- Replace ts-node with tsx for better performance and compatibility
- Add --dry-run flag support for CI syntax checking
- Relax TypeScript strict mode for third-party type incompatibilities
- Add explicit TypeScript type annotations for better type safety
- Apply Prettier formatting to improve code consistency
- Fix type casting for viem/account-abstraction compatibility
- Update dependencies in pnpm-lock.yaml
