Implement the new ML API and the bump ML hash

- Bump Medialibrary Hash

- ML: refactor EntryPoint(s) to Root(s)

This is to follow the renaming that happened in the MediaLibrary

- ML: Update after ML API incoherence fix.

This concerns a confusion with Subscriptions and Services
and especially the cacheSize / cachedMedia which was messier before the
recent update.

Fixes #3027
