feat(mirror,create): make MIRRORS single source of truth and exclude PyPI from git config

- Treat MIRRORS as the only authority for mirror URLs
- Filter non-git URLs (e.g. PyPI) from git remotes and push URLs
- Prefer SSH git URLs when determining primary origin
- Ensure mirror probing only targets valid git remotes
- Refactor repository create into service-based architecture
- Write PyPI metadata exclusively to MIRRORS, never to git config
- Add integration test verifying PyPI is not written into .git/config
- Update preview and unit tests to match new create flow
