PlaceOS::Model::GroupSignageTemplate::PrimaryKeyType
Overview
Junction between Group and SignageTemplate (both authority-scoped,
UUID). Same M:N shape as GroupPlaylistItem — allows templates to be
shared with groups so they can manage their own templates.
Presence-only — no per-row permission bitmask, no GroupHistory audit.
A user's capability on a linked template comes from their
GroupUser.permissions within the group.
Both sides must share an authority — enforced here at the model layer (no single FK can express it).
