refactor: clean up code and improve type-only imports

- Remove unused node server initialization
- Fix missing commas in function parameter destructuring
- Use `import type` for type-only imports across payload files
- Ensure consistent trailing commas in functions and tests
- Improve error messages in get.route.ts
