refactor(api): simplify instance management endpoints

- Change delete endpoint to use request body instead of path parameter
- Modify endpoint now takes field as path parameter and instance name in body
- Update README to reflect API changes
- Remove unused description field from software info
- Fix error message in auth token lookup
