feat(auth/user): Finished User Rework to handle Guest

- Split userinfo APIs to their own service (`user`)
- Added user service to nginx and docker-compose
- Cleaned up package.json across the project to remove useless
  depedencies
- Added word list for Guest username generation (source in file itself)
- Reworked internal of `user` DB to not have a difference between "raw"
  id and normal ID (UUID)
