feat: add configurable pageSize option (#14)

Allow users to customize the number of repos displayed per page via config:

  # ~/.config/git-scope/config.yml
  pageSize: 25

- Add PageSize field to Config struct with yaml tag
- Default remains 15 if not specified or set to 0
- Model now reads pageSize from config instead of hardcoded value
