Relative URL allows CI to use the same access method as the main repo,
avoiding networking issues with absolute URLs.

- Add wc-licensed-product-client as git submodule in lib/
- Change Composer repository from VCS to path type
- CI now checks out submodules recursively
- Remove COMPOSER_AUTH (no longer needed)
This solves the CI networking issue by fetching the
dependency via git submodule instead of Composer.
