feat(cms): extract all-releases grid as embeddable ALL-tab component (9.8.B)

Browse Source 
CmsAllReleasesGrid self-loads the cross-medium release list so 8.A can host it as the ALL tab with no VM plumbing; TrackList's Albums mode renders it now. Preserves sort/delete/expand/edit and the 8.D Type chip.
